[Serusers] SER and RTPproxy

[Jeff Russell]

I Think I have thing configured correctly and yet I can not make  
things work correctly.

This is what I am do

I have SER on an internal (10.1.1.x) IP address
I have RTPproxy on a different machine with a public IP address   
206.75.15.x

I am routing the call out over our firewall and things 'almost' work.

SER sets up the call using the RTPproxy to set up the ports for the  
RTP stream, and the RTP stream is returned from the far end to the  
public IP address, however non of the RTP traffic is sent to the  
internal address, I am guessing it is waiting for an rtp stream from  
the internal address but neither SER nor the ip-phone send anything or  
even seem to know about the RTPproxy.

Can anyone offer ANY suggestions as to how to direct the internal RTP  
stream to the RTPproxy address?


Many thanks,

Jeffr
