I’ve run into an Echo issue and don’t seem to be able to find a solution.
I’ve done quite a lot of searching and readin but sitll don’t seem to be able to find an answer to my issue.
Basically I have and Asterisk / FreePBX box that has 3 SIP Trunks (2 google voice and 1 CallCentric).
For extensions, I have 2 SIP extensions to a Linksys WRTP54G and 2 SIP extensions to SIP desk phones.
When I make calls to the SIP desk phones from either a Cell Phone or PSTEN I do not hear any echo and the sound quality is good. When I make calls to the extensions that are coneected to the WRTP54G I get echo occuring. This occurs regardless of the incomming SIP trunk.
I’m at a loss as to what to do here. I know it’s not the analogue phone itself as it used to be connected to the WRTP54G and used with Vonage.
