Polycom is a leader in the IP communications space. Not only are their longstanding SoundPoint series of desktop IP phones class leaders, but their voice technology can be found in many products under many names.

Seeing a need to expand their product offering to include cordless mobility, Polycom recently acquired SpectraLink, a leading maker of Wi-Fi-based telephony systems, and Kirk Telecom, a leader in DECT-based cordless telephony systems. These acquisitions, now consolidated under the Polycom name, give the company a comprehensive product suite addressing the mobile IP communications needs of various vertical markets.

Asterisk to Support Polycom’s Siren7 and Siren14

asterisk1Just a brief news item from my notes of the December 26 VUC call with Steve Sokol. We learned that Digium is planning support for Polycom’s Siren7 and Siren14 codecs in a future release of Asterisk v1.6. These are also known as G.722.1 and G.722.1 Annex C. They offer wideband calling at bitrates much lower than G.722 calls.

Siren14 supports bitrates of 24, 32 or 48 kbps and 14 khz passband making it equally well suited to music as voice applications. Siren7 supports bitrates of 16, 24 or 32 kbps with 7 khz passband.

VUC Call Dec 12: Asterisk Security

polycom_ip650_256Let me be amongst the first to say that I can be such a schmuck some days! Randulo asked me to guest host last Friday’s VUC call as he was unavailable. I agreed since I was going to be in my office that day. I thought ahead enough to have the correct Talkshoe web login to get the conference started.  But I called into the conference server using my usual SIP dialing process. I have it programmed into my hosted PBX, so it’s routine.

Logged in as me, and not the call host, this didn’t allow me to initiate the call recording on the Talkshoe conference bridge. Of course I didn’t know this until a few seconds before the call was to begin when I first tried to start the recording. No problem, says I, I’ll do it locally…which I did. I recorded the call using my Polycom SoundPoint IP650, which I used to actually participate on the call.
