Call Distortion on OG calls.

[wizkid66]

Hi All,

MiVB 10.1.0.29
MiCollab 9.8.2.12-01 (Server)
MiCollab 9.8.204 (Windows Client)
Teleworker MBG 11.5.2.31
Sip MBG 11.5.2.31.

Clients running on Windows 10.

All our users are MiCollab soft phone users.

We are experiencing a problem with some outgoing calls, when the external party answers they sound robotic to us, but we sound fine to them.

We initially thought this was our sip provider, but they have monitored our calls and cannot hear any distortion.
I have listened back to our recorder (Red box, using MiCollab as the SRC) and that also sounds fine.

Does anyone have any idea's or pointers, this has been going on for a while now, and is driving me crazy.

Many thanks,

Stuart.

Change the codec type for the sip trunks

Thanks for the pointer, what would you change it to?

It is a wave form compression issue. Caused either by sip trunks or ip phones
Either way it is a codec issue more than likely.

Did this fix your issue?

I will be onsite tomorrow, so will be able to look to see if this resolves the issue.
Thanks for your help.
