[asterisk-users] TDM2400P and Polycom phones

[Robson Ribeiro]

Dear All, thanks for the help on the TDM2400P. I have resolved the issue. I
isolated the problem and ended up finding out it was the Polycom phone that
had a problem. Those phones have spectacular quality but they are way too
complicated to setup. Also, it's absurd Polycom only supplies you with the
latest software if you ask through your reseller!!! What kind of rule is
that? Is someone making Polycom phones in China other than Polycom. Well, in
any case the phones got confused when selecting the right CODEC to use so I
isolated Alaw and....DONE. The TDM2400 is fine and works perfectly and so
does the phone. One note to people trying to install these phones is that
there is a guide on VOIP-Info for the IP500 (more expensive) but not for the
Ip301, but they are the same. The other things is that this phone doesn't
like to talk to other phones on different networks (like connecting your
office and your home with the same phones.

Robson

I apologize; I failed to realize you were non-CONUS; the CNID was
odd-looking, and I ignored the call.  Feel free to try again.

Can you try originating a call out your FXO port from a SIP phone?

Is the audio ok when you call FXS to FXS?

You need, in general, to use the process of elimination to figure out
where your problem *can* be -- even if that entails borrowing hardware.
