I have an asterisk 11.4.0 server with two interfaces, eth0 and eth1.

Eth0 has a default gateway on it, eth1 is connected the subnet that has my phones registered.

I’d like to use the multicastRTP driver to do paging. However, when a phone dials an extension with multicastRTP, the multicast stream goes to the primary interface (eth0) and it really needs to go to eth1.

Is there a way to specify which interface the rtp is sourced from?
