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? Matt Hoskins | NPG Corp | Systems Architect 816.749.2815 -------------- next part -------------- An HTML attachment was scrubbed...
