|
|I have a number of IP600s and 601s that I was experiencing 
|occassional echo with.  I recently upgraded them to firmware 
|1.6.5, and rather than using my existing sip.cfg/ipmid.cfg 
|that had been around forever I started fresh with a completely 
|stock 1.6.5 sip.cfg file.  My echo issues have disappeared completely.
|
|With the 1.6.5 version of the Polycom firmware the default 
|value for voice.gain.tx.analog.handset="12".  The default 
|value for voice.gain.tx.analog.headset="3".  I suspect you 
|should update the entire <voice> section of the file (if 
|you're not ready to start from scratch) since it contains 
|default values for AEC, AES, NS, AGC, RXEQ, and TXEQ.  I have 
|pasted just the <gains> section below in case anyone want to 
|compare it to their current settings.
