Details posted to asterisk.bizAs there has been interest expressed in conferencing applications on the Asterisk-biz list of late, I thought I'd draw attention to our CNX conference bridge appliance, which supports up to 120 concurrent users over VoIP or TDM links. More information can be found here, but the main highlights are these:
- PowerPC-based architecture running custom Linux distribution (<20 MB), with Asterisk providing basic call processing
- 4 x T1/E1 spans, supported using a Zaptel-compatible driver, with PRI and RBS support
- Vocoding done using a dedicated DSP, supporting 64 channels of G.729 or 120 channels of G.711 (all codec licenses are included with the system)
- SIP and H.323 support
- Conference mixing, echo cancellation, DTMF detection, message playout, automatic gain control and noise suppression provided using a dedicated DSP
- All storage uses Compact Flash; a single fan is the only moving part.
- 1U high appliance, runs quietly and cool
Note that this is not just an out-of-the-box Asterisk implementation — we have created a tailored package containing Asterisk, other open-source applications, libraries and supporting frameworks alongside our own custom application to provide a complete, read-to-run conferencing platform. (For developers, source code is of course available per the terms of the GPL, LGPL and other open sources licenses included in the product documentation).
