You are confusing two things. TI makes the TNETVxxxx range of chips. Their Telogy division makes software for VoIP platforms. The two may be used together or apart, and things may be added to the basic set of Telogy software. For example, in the Linksys SPA series you'll find the TI silicon used with Telogy software, but they also have Asterisk thrown in there to provide voicemail features.
I very much doubt that Polycom uses TI's software. They've had their own VoIP software for a very long time, and I expect they still use it.
