I am in need of help. We currently are running a vMCD version 6 SP2 and our PRIs are located on a 3300 running the same version. We have setup Lync for IM and conferencing and when you call the internal extension (4510) everything works fine. It is also a known DID but when we call it from the outside it gives back an error message saying the number is no longer in service. I am new to SIP trunking and I was wondering if I needed to put a SIP trunk in the ICP 3300 or will the number route from the PRI gateways to the vMCD to find it path.
Thanks!
