Our telephone server allows you to integrate voice communications throughout your entire facility by enabling both IP, Digital, and Analog trunks and extensions on the system. This means a regular conference or cordless phone may be connected, or a feature rich IP phone. You may have true IP communications to the world, or be connected via traditional phone company lines or T1. You may connect your offices together using native IP technology, or create an analog bridge. Our system is so flexible anything your organization needs is either already included, or can be custom programmed into it. From advanced autoattendants to true database and software integration, our PBX allows a seamless integration of your phones for your clients.

• Auto-Attendant (IVR): The OSSI Auto-Attendant lets callers "Press 1 for Support" or "Press 2 for Sales." The Auto-Attendant feature is easy to use and powerful. With simple clicks of the mouse you can manage call flow, build scheduled responses, forward calls off-site, and more.
• Outlook Integration: * Inbound Calling: When your phone rings, the Caller ID will be analyzed against your Outlook contacts. If a match is found you will see the person's name pop-up! * Call from your inbox: Right-click on a contact or email message to call. Your phone rings and you're connected!
• Voicemail: OSSI offers four easy ways to retrieve messages:* Press a single button on your office phone. * Dial in remotely from any outside phone. * Receive attached .wav files in your email. * Listen via your Web control panel.
• Voicemail-to-Email: Receive your voicemails as emails! OSSI comes pre-configured to send each employee an email whenever they get a voicemail. You can even have the audio attched to your email so that you can listen to the voicemail right from your Inbox. No POP3, SMTP, IMAP, or Exchange configuration required!
• Hot Desk: Have more agents than you do desks and phones? No problem! If you have Call Center Edition, queue calls can be received on the phone that you are logged into.
• Music on Hold: Music-on-Hold (MOH) is as simple as uploading MP3 files using the web-based administration panel. OSSI PBX comes with multiple playlists, giving you the ability to play different audio tracks for calls coming into different departments or queues. Use MOH creatively to highlight promotions to new customers, up sell current customers, or assuage angry customers calling your support team.
• Scheduler: Want to play different messages to callers at different times of the day? Want an entirely different Call Menu on weekends, with different options for your callers to choose from? Use OSSI's intuitive Scheduler to create and apply schedules that will make your phone system work for you - even when you have gone home for the day!
• Night Mode: Have a small office that opens when your first employee arrives and closes when your last employee leaves? Night mode is a feature for companies that want to "turn on" their phone system in the morning with a few key presses and put it to night mode and the end of the day with a few key presses or setup a speed dial button on your phones for one-touch switching of mode.
• Custom CTI (AGI): On the surface, OSSI PBX is the world's easiest to use enterprise PBX. Under the hood, it can do all sorts of custom things such as database dips, CTI integration, Internet look-ups (RSS feeds), text-to-speech, and more.
• Analog & IP Phones: OSSI PBX is one of the most flexible phone systems on the market today, supporting all analog phones and numerous IP phones such as Cisco, Polycom, Aastra, SwissVoice, and Snom. OSSI PBX supports MWI (message waiting indicator) on all IP Phones and utilizes stutter-tone on analog phones to indicate voicemail waiting. Analog phones support multiple call appearances via call-waiting flash-hook. For the best support and integration, use our .
• Ring-all (Blast Group): A Blast Group takes one inbound call and rings all phones; the first to pick up gets the call. This feature, on other phone systems, is sometimes called "Simultaneous Ring".
• Call Forwarding: Users can employ their personal Web Control Panel to enable call forwarding to either an internal extension or to an external number.
• Name Directory: OSSI PBX comes pre-configured with a professional "spell-by-name" directory. Callers are simply prompted to "spell the first three letters of the party's first or last name." They are then automatically connected to the requested extension. Don't want to be in the Name Directory? No problem. The OSSI PBX administrator can easily exclude certain extensions from the Name Directory. Linked Servers (e.g. branch offices) now have linked Name Directories too!
• DIDs: Have more employees than phone numbers? With one click of the mouse, you can assign an inbound phone number to an employee.
• Unlimited VoIP accounts: OSSI PBX comes VoIP-ready with unlimited VoIP provider accounts for all editions. With a couple clicks of the mouse, you can connect OSSI PBX to your favorite VoIP Providers (SIP or IAX) and configure VoIP for inter-office and intra-office calls while keeping regular calls going out over POTS/PSTN. We recommend using VoIP for free inner and intra-office calling, and perhaps to save on international calling, but to stick with PSTN if you can afford to. However, if you are going to use VoIP as your primary provider, we highly recommend:
• PSTN Fallback: OSSI PBX offers VoIP-users a PSTN back-up in case of an Internet service interruption. Virtual PBX products offer no PSTN back-up, so, if your Internet service goes down (there is no 100% guaranteed up-time), your business telephone line goes down with it - which is unacceptable in a dynamic business environment. PSTN-Fallback is automatic. trixbox Pro detects poor (or zero) Internet quality and immediately steps your system into PSTN mode. Note: OSSI PBX runs in PSTN-only mode if desired. No VoIP required!
• Telecommuters: Telecommuting is the way of the future - proven to increase employee satisfaction and effectiveness. You'll be glad to know that trixbox Pro was built with telecommuting in mind. With an IP phone (or softphone), employees can keep their extension number as they travel outside the office or between offices. No configuration changes required. You'll never again have to leave the message, "I am out of the office today." From your home, a hotel, or even your cell phone you'll be able to answer your extension as if you were still glued to your cubicle!
• Branch Office Support: Deploy a low-cost OSSI PBCX server in each office. Then, with a few clicks in your control panel, link your servers to take advantage of the following features: * Free office-to-office calling via VoIP. * Call forwarding to any extension in your linked trixbox Pro server network * Converged Name Directories (spell-by-name) * Converged Internal Employee Directories * Shared agents and queues (Call Center Edition only)
• Web Control Panel: Our award-winning Web interface comes in two flavors: * An admin panel for administrators -- manage all aspects of trixbox Pro remotely. * A user panel for employees -- allowing them to manage their personal configurations (such as listen to voicemail, click to call people back, enable call forwarding, etc.) from anywhere in the world.
• Powerful Reporting: From the OSSI PBX Web Admin Panel, you can analyze real-time call logs for all extensions using powerful search and filter parameters. OSSI PBX also provides real-time billing (available for those who use our VoIP network) so that, at any time, customers can see a snapshot of how much they are spending company-wide on telephone calls. From the OSSI PBX Web User Panel, individual users can look at their call logs - and return calls with the click of a mouse!
• Hands Free Auto Phone Provisioning: Just by connecting your phones to your network, extensions will be created, configuration files for your phones generated and your phones automatically assigned to the new extensions! Hands free phone auto-provisioning is supported on all supported Aastra models, Cisco models, Snom models and Polycom models with firmware 2.2 and above.
• Fax Support: Have a fax machine or fax server and want to send and receive faxes through OSSI PBX? No problem! Whether you have a dedicated analog line for your faxes or a PRI, simply connect your fax server or machine to PBXtra, and use OSSI PBX's web-based Control Panel to assign a phone number to it in just a few clicks.
• BLF (Busy Lamp Field) Support: You can now view whether other users of your phone system are on the phone directly from your phone! Using the Company Directory, you can easily drag-and-drop users into your BLF area on any Aastra model with BLF support. We have even added automatic detection and support for the Aastra 536M and 560M sidecars to extend the number of BLF keys available on your Aastra phone.
• BRI Detection: We now have auto-detection and auto-configuration of Sangoma BRI cards. That means when you put a BRI card in your system and scan for new cards, the BRI will be auto-configured and in most cases be ready to use.
• E1 Support: As well as auto-detection of Analog and Digital PRI cards, OSSI PBX now features the ability to support E1 circuits. This now allows many people in other countries to utilize higher end phone circuits with OSSI PBX.
• Live Backup Server: When you need fast and simple redundancy LBS can help save the day. By using LBS you can have a complete hot spare system online and with just a few seconds of configuration in the OSSI PBX control panel you can easily switch over to the backup machine.
• Rebrandable Interface: OSSI PBX is the first trixbox telephony application platform that provides easy branding capabilities through a powerful administrative interface. In OSSI PBX, resellers and customers can co-brand the product by uploading images and choosing color palettes. OSSI PBX support full re-branding capabilities.
• Conference Bridges: Conference bridges were once thought to be unaffordable for many companies, but OSSI PBX comes pre-configured with conference bridges for free! A OSSI PBX conference bridge supports an unlimited number of internal participants and as many external participants as you have phone lines. Using WebAdmin you can even, at a glance, see who in your company is speaking on a conference bridge!
• Extension Groups: Your organization may not be flat - meaning that some employees have communication responsibilities that others do not. OSSI PBX includes a powerful "groups" feature that allows you to build extension groups and assign permissions to those groups. Examples of OSSI PBX permissions are: * Zone Paging/Intercom * ACD - Record other's queue calls * ACD - View queue reports * ACD - Agent login / logout * Call Forwarding * Check Voicemail * Dozens more! OSSI PBX includes "group permissions" , enabling over a dozen additional "permissions", such as: * Barge * Call Privacy (who's talking to who) * Block call "stealing" * Record my calls * Many more
• Routing by DIDs: Your business may have several numbers for different departments. With OSSI PBX's ability to route by DIDs, you can direct calls to a different call menu based on the inbound number.
• Paging/Zone Paging: Want to page everyone in the whole company or just a certain set of employees? Simply build a "group", assign that group an extension number and begin paging them!
• Intercom/Zone Intercom: Many telephony products offer an intercom feature, but do you know of any that offer Zone Intercom? OSSI PBX does! With OSSI PBX you can dial a zone to setup an ad-hoc conference with everyone in that zone!
• Voicemail Groups: Want to send a voice message to multiple people? Use the Voicemail Group feature to easily build groups (such as your sales team). Then dial the number of your group, just as you would normally dial an extension, and leave a message. Seconds later, everyone in the group gets your new message!
• Advanced Call Forwarding: With a few clicks of your mouse you can forward an extension to another extension, a cell phone, or even to another part of your Auto-Attendant. This let's you build very creative IVR trees to meet the needs of your business.
• Call Return: When listening to their voicemail, your employees will be able to press a key to call the person back. You can enable or disable this feature on a per-employee basis.
• Call Out: When accessing OSSI PBX's voicemail system, your employees will be able to make an outgoing call. This can be a great toll-saver, allowing "billable" calls to be kept within your domain. You can enable or disable this feature on a per-employee basis.
• Report Exporting (.csv): Extend OSSI PBX's powerful reporting engine by creating .csv files that you can import into applications such as Excel and Access.
• Custom Caller IDs: OSSI PBX lets you customize the inbound Caller ID name/number for each department and it lets you change your outbound Caller ID on a per-extension basis, allowing you to block, reveal, or change the Caller ID of every extension in your office! Note: OSSI PBX cannot change your outbound Caller ID if you are using POTS lines. For 911 reasons, POTS outbound Caller IDs are always controlled by your carrier.
• IVR Authentication: With a click of the mouse, you can password-protect any part of your Auto-attendant. Use this feature to protect your Conference Bridge or your priority queues.
• SMS/Pager Voicemail Notify: This feature gives you the ability to enter an SMS or Pager email address in order to receive voicemail notifications on that device. These notifications are short and do not include the actual audio attachments. This feature can be used in conjunction with the Voicemail-to-Email feature. Thus you can receive email alerts (including optional audio attachments) at one email address and simultaneously receive SMS/pager notifications at another address.
• Upload Voice Prompts: This feature gives you the ability to upload highly professional pre-recorded voice prompts when simple recordings from your phone just won't do.
• Alerts & Notifications: Administrative alerts and notifications allow administrators to set desired operating thresholds for a OSSI PBX deployment. If the system operates outside of these thresholds, the administrator is instantly notified.
• Trunks Status Pages: View the real-time status of trunks in the administration control panel to ensure that your digital and analog PSTN interfaces are operating correctly. Here you can quickly see whether your cards are connected, determine whether they have alarms, view the PRI status, and more.
• Real-Time System Resource Graphs: OSSI PBX offers highly detailed graphs of system resources (CPU, RAM, HD, Swap), server activity (Calls, Recordings, Conferences), and network activity (upstream, downstream).
• Follow Me: Allow callers to find you wherever you are: on your cell phone, at home, or at a branch office based on rules you create. Make FindMe work for you with various features such as: a scheduler, simultaneous ringing, and privileged lists. Our new FindMe feature is even smart enough to sense when you have walked away from your desk and thereby ring you on your cell phone. Not only can this be used for individual extensions, it's also a way to create small rings groups. This can be used, for example, to have a secretary's phone ring at the same time as the boss' phone.
• Mobile Integration: Mobile Integration allows you to send a call that has been forwarded to your cell phone right back to any extension on your trixbox Pro. Simply press a few keys on your mobile phone and... presto... that call is redirected to your assistant or back to your own desk. You can even record calls on your mobile!
• Call Screening: Call screening allows you to talk to who you want, when you want. When you enable Follow Me on your extension, optionally use call screening to screen the calls that are forwarded to your mobile, home, or other phone numbers. Before the call is forwarded, the voice prompt will ask the caller to record their name, and that recording will be played to you before you accept the incoming call. OSSI PBX takes call screening to the next level!
• Unlimited Call Queues: Each queue comes with a variety of options: * Personalized audio announcements give your queue a professional sound. * "Hold Time" announcement frequency customization allows you to tailor your callers' on-hold experiences. * User/Agent priorities allow for more effective call routing. * Hold time limits ensure that callers do not remain in your queue for extended periods. * Caller limits keep queue call volumes within manageable levels. * The ability to set the length of time after fielding a call before the same agent is called again improves agent productivity. * Much much more!
• Full Featured A.C.D.: A.C.D. (Automatic Call Distribution) allows you to route incoming calls to your users/agents in many different ways to facilitate your unique business needs: * Ring all - 1st to pickup gets the call. * Ring one person at a time in order. * Ring in order, with memory. * Ring who was least recently called. * Ring who has the fewest calls. * Ring a random person.
• Skills-based Routing: Assign each agent a priority and your queue will distribute calls to them accordingly. This means you can pass more leads to your star-closer, or pass fewer leads to your underperformers. OSSI PBX offers an additional layer of prioritization based on agent order. This means similarly skilled agents can receive calls in an ordered, round-robin fashion.
• Agents on Cell Phones: Remote agents on cell phones or analog home phones can now seamlessly participate in your queues. This means that callers will never know if the answering agent is on an IP phone in your office or on a mobile phone in another part of the world!
• Agents Shared across Sites: You can have agents across several branch offices participate in the same queue.
• Real-time queue Stats: Want to know how many callers are in your queues? Need to know which agents are logged in? Need to know which of your agents is already on a call? The OSSI PBX Web-based control panel answers all of these questions, helping you to manage your queues with real time stats.
• Full Web-Based Administration: Check voicemail, call recordings, change settings, configure your entire system, transfer calls, view extension and queue status, park calls, and manage every function of the system directly from your web browser!
