Hi one of our clients is experiencing echo problems with their calls.
They here themselves in echo.
The person they are calling or receiving call from does ot hear any echo.
And the echo they hear is not from that person also.
Here is what I mean
VVX (caller) -> Callee
Hears an echo from them (caller)
Does not hear echo from callee
No echo at all
Same behavior is noticed if it's an incoming call.
We are runing those phones on the latest firmware and using FreePBX.
Our line are POTS with Sangoma VEGA50.
We tried with the Sangoma NetBorder Express solutions and Patton SN4114 and we are experiencing the same problem.
We really need help to figure this one.
Hello Francois Collerette,
welcome back to the Polycom Community.
Did you ever find a resolution for your initial post => here <= ?
It is always useful to include the currently used SIP or UC Software version as issues experienced may already be addressed in a newer release.
We the community are unable to know what you mean by latest as this depends on when you posted this query and whatever the SIP PABX maintainers believe is the latest software.
The above may not be true to a Polycom released version.
The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"
Therefore the Polycom VoIP FAQ contains this post here:
Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?

Hi Francois, bonjour François.
Did you found your issue about echo with VVX410 ?
We are experiencing the same issue with VVX410 for the first 2 seconds on a incoming call. Our customer listen echo from her phone (her own voice) for 2 seconds and sometime, more longer.
You can reply in french if you spoke french.
Thank you in advance.
