What I am observing is that Media is not terminated on the acme sbc. It seem to be that the sbc is just proxying all sip signaling messages and not terminating media. I would imagine that there must be a way to make it terminate media like CUBE does otherwise the purpose of demarcating customer network from outside world is defeated.
Question is how do i achieve this? Is there a configuration that I need to enable on the e-sbc to force it to terminate media and send its IP in the SIP SDP rather than the IP addresses of the endpoints to each other.
NB: Both CUCM clusters are in seperate realms and have separate sip interfaces
