Hello Folks, I am looking for a way that makes Asterisk tell remote SIP
party that the IP where they will send RTP is not the same as the one I am comunicating via SIP
Can this be done anyhow?
I can try and explain:
We have placed a asterisk box in our partners office.
It has eth0 with IP 172.16.1.10 and eth1: 10.34.18.250
linux has its routes set so it can comunicate with several networks in their offices.
now there is a cisco call manager that we need to communicate with. Normally via our IP 172.16.1.10, however seems that this cisco uses some sort of ‘directmedya=yes’ and sets both ends speaking RTP with themselves.
There are some extensions in cisco that have a network 10.134.0.0/16 that we can only comunicate via eth1
thus when calling cisco (always via eth0) sometimes we need to say that OUR
IP to recieve RTP is not 172.16.1.10, but 10.34.18.250
can this be done?
