[Help] Polycom IP500


I’m trying to configure one of these to work with my asterisk server. I’m using the bristuff-0.3.0-PRE-1 distribution.

The server works fine with several softphones.

I have configured the phone correctly and according to the phone log it is trying to register, but in the phone log I get the message Error Code: 405 Method Not Allowed.

Could anyone shed any light on this ?

Many thanks in advance.



Try turning on ‘sip debug’, it might spread some light on what your phone is trying to register with.

Setting up polycom phones is not very easy. I had lots of problems with my polycom ip500 until I found this page:

voip-info.org/wiki/index.php … int+IP+501

It’s instructions for the ip501, but they are the same for the ip500. The ip501 is the same phone as the ip500, except that it has more memory.

Be certain to follow the steps exactly as described. Pay particular attention the instruction to “reset to default” and “reset local config”.

I tried skipping those steps and spent more time than I should have on my ip500 installation.
