Sounds like it could be clipping due to canceling echo on the POTS line. Just my 2 cents... non refundable btw.

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.
