Users called by softphone have bad echo of themselves

[usa4148]

Hi Guys,

I have what appears to be a configuration bug - My setup is listed below. I am using Aastra 9143i in a small office pbx.

I am trying to use a softphone - I've tested Zoiper, X-Lite etc.
When I call anyone from the softphone - inside or outside the switch - the person I call has a bad echo of them self, delayed almost 2 seconds in their own ear piece.

Doesn't matter if it is a call phone I am calling or another extension in the office.

I loaded up the config on a VPN install of PIAF and the bug followed the config. Then I wiped the config and did a scratch config with a test trunk (same provider) and it went away. So its in my config.

Is there a way to just Disable the called user's local Echo?

Thanks Heaps,
Cya,
Dan

Well - I figured it out -

I disabled Echo cancellation in the clients and changed DTMF to inband. Not sure the latter mattered. Local echo in the callee's ear is gone.

'Doh
