[asterisk-users] RTP IP re-write

[Thomas Kenyon]

I am having a problem trying to get a particular softphone working on my 
setup.

The machine it runs on has more than one interface. When the softphone 
registers, it registers fine, and asterisk is given the correct IP for 
registration.

Whenever RTP is set-up however, the client gives the wrong IP to connect 
to and I get the inevitable problem with one-way media.

Is there any way of forcing that SIP account to have the rtp always sent 
to a particular IP. (I know that this still may not work, because the 
device is probably listening on the wrong interface as well, but it's 
worth a try).

I haven't been able to get a response from the vendor of the softphone.
