Extension Echo

[robhicks]

We're testing 3cx. We've set up the pbx on a fairly beefy computer - 2 processors, 2GB ram, etc.

We're getting a terrible echo between extensions.

In a sip system, doesn't the pbx just negotiate the connection and then get out of the way? Or, does all the voice traffic go through the pbx?

Yes - unless you've got the extensions bound to the pbx. What sort of phones have you got ? Also - is the echo internal and external or just for external calls.....? I've found horrible echo problems when the handset gain is increased along with high handset colume. You end up with the beginnings of a feedback loop. If you're getting echo when you're running test calls it may simply be a gain issue. I think we need a bit more info.

You may take a look to the "Server status" page in user interface.
"MediaServerReporting" provides information about mode of RTP connection.

Anyway, PBX DOES NOT modify audio content

Thanks

All,

Thanks for your help!

The issue is both internal between extensions and on external calls -- but I've been trying to focus on what's going on internally.

We're using GrandStream GXP2000 phones.

What does it mean that calls do not go through the PBX unless you've got the extensions bound to the pbx? I have added extensions by pointing them at the PBX.

Yes - unless you've got the extensions bound to the pbx.

I'm not in the office right now to do some tests and then look at the RTP connections but I'll take a look on Monday.

Thanks again for your help!
