hi!
i have my provider delivering 120 sip trunk channel to mivoice 5000, from there i'm able to transfer blind and supervised to all other sip trunk.
When i try to do the same to another site that has CUCM 7.1 they are able to hear me from the external, but i'm unable to hear them.
all site are on the same MPLS, and reachable, no middle blocks by ASA or other firewalls.
Any thoughts.
