I have the following situation: Asterisk 1.2.1 25+ Polycom 501 telephones. Bootrom 2.6.2.0032 Application 1.6.2.0041 Some 501's local to my network, some across the great INTERNET divide. PRI connected to Sangoma card. Issue: horrible echo (and squeals, and "underwater-like" sound) on speaker phone when calling from extension to extension. echo not present when calling outbound using PRI or when receiving calls from PRI. echo not present when using handset or headset in any case. All gains, etc. are as listed in the Polycom Admin Guide. Not specific to any phone, or its location on our network. I suspect the issue is related to the echo cancelation HW in the speaker phone, but I'm not sure...The unfortunate thing is these phones were purchased because of their excellent speaker phones which now appear to be worse than the Grandstreams! Anyone with thoughts of where to start? TIA - Jeff H.
You aren't making calls from one phone to another, with them right next to each other on the same desk are you?

I have had the same issue. It has a lot to do with the acoustics, as well as gain. Before I messed with the config files it sounded great, then I fussed with them and upgraded to the latest sip, and now I also notice this on speaker. I would go totally default, local configure and see how they sound...

IMHO, that is normal and to be expected.... I can't remember the technical name right now, but if you can create a 'loop' in the audio between the speaker of one phone and the mic of the other, then you will get this result....> Anyone with thoughts of where to start?Move the phones further apart, turn down the volume of the phones, don't use speaker :) Good luck, perhaps I'm wrong, and the above should work....

I would hate to have to go back to the old firmware. Although Polycom recommends keeping the older bootrom unless you need https provisioning, I'm going to try the new bootrom and see if it fixes the problem.
