[Serusers] xten and Mitel 5055 - sr-users

4 Dec 2003


      Hi,
apologies for using this email list for something which is not directly 
linked to ser.
I'm having a weird problem when setting up a voice connection between an 
Xten X-Lite UA and a Mitel 5055 SIP phone (connected via a ser proxy 
server). The session initiation is all fine, but the media session is 
not - the voice transmitted sounds a bit like a robot and is impossible 
to understand. I assumed this is a codec problem but strangly this 
problem ONLY occurs between the Xten UA and the Mitel phone. It does not 
occur between Xten and a Pingtel phone nor between Mitel 5055 and 
Pingtel, nor between Ubiquity UA and Mitel 5055. As far as I know all 
use the G711 codec.
Has anybody experienced this problem also?
Thank you for your help.
