Hi,

I am new user for Fusionpbx. I have installation done and incoming call - outgoing call is working fine, but call is echo. how can I solve this issue ?

my FreeSWITCH version: 1.10.6-release-18-1ff9d0a60e~64bit (-release-18-1ff9d0a60e 64bit).

Thanks.
 
You should look for the issue outside the Freeswitch. I would follow this path.

See if your device has a calibration for echo cancellation.


Make sure all your devices are setup to use ulaw/g711 codec unless for WebRTC which would be Opus.

Make sure your carrier is also using Ulaw/G711.

Finally, test it with a good desktop phone or desktop software.
 
Can you give full information on how you are testing the voice?

Internal calls? External calls? On mobile phone, desktop computer, are testing alone, are you testing with another person? Inside the same room, apart from each other on different networks?

FusionPBX install on vps then create extension like 101 this location register Australia laptop 3cx soft phone. And another extension 102 is register on another location (Bangladesh) on 3cx softphone.
when I try to call 101 to 102 is the same echo problem.
when I try to call local number from extension 101 to Australia local number then face same issue.
I think its issue is FreeSwitch. But I can't know how to solve this issue.
Yes, different network.

Thanks.
 
When you try to call the local number in Australia, are you hearing the echo or the other side complains? Can you test calling from Linphone desktop to Australian local number and while on call check the stats for jitter, pocket loss etc.
 
When you try to call the local number in Australia, are you hearing the echo> Yes.
Also try to call SIP provider call center as the same issue.
No any packet loss.


Thanks.
 
brother, already answer this question. 101 this location register Australia laptop 3cx soft phone.

Please see again.

Thanks.
