Subject: [Asterisk-Users] Polycom 600 problem

Hi there,

We are using 10+ Polycom SP IP 600 phones with Asterisk and TMD400P with 
4 FXO lines.

So far we have 3 phones with following problem: more or less frequently, 
for every call or ever other call, user of the phone would hear brief 
interruptions on the line when dialing out via PSTN, like if someone 
would be disconnecting and reconnecting the external line a few times 
per second. At the same time Asterisk Voicemail, Music on hold, SIP to 
SIP calls would work just perfect. Loud and clear.

It is not dependant on network conditions, network configuration, 
extension number, PSTN phone # dialed or particular network location of 
the phone. So it is a problem with the phone. I've tested this quite 
thoroughly: if I install a different 600 phone - that one would work 
just fine at the same locations/extension/network connection etc. Cisco 
7940 does not have this problem either.

I already RMA-ed one of the Polycoms and looking to return the other 2. 
Meanwhile, if someone can comment on this problem, that would be a great 
help!

Other than this problem, the Polycoms 600 are excellent for Asterisk setup.

Thank you,
Andrei
