Do we need to bind sip control and media source with different interface?
Also, which interface do i need to bind
I have a sub-interface which tag the voice VLAN and DHCP, and I also have a WAN interface which there is a sip trunk to the CUCM.
Question 1: Are these for the usage of registering SIP phones?
Question 2: Do they need to be set under SIP Trunk?
