I have a machine with three IP addresses. NIC eth0 NIC eth1 and a virtual address on ETH1 All my devices work normally communicating to the virtual address on eth1. My question is just for mulitcast. The end device has an option for "allowed source" so I put in the virtual address from my server. No multicast audio received... I then disabled the "allowed source" and tried again. I received multicast audio. My question is how do I set on Asterisk 11.15.0 the "source address" for multicasting? In my sip.conf I do have the "bind" parameter set to my virtual address.
