I have a problem where I answer an inbound call on my E1 PRI and then transfer the call off-net over the same E1 PRI. It seems that CUCM does not fully release the call and two channels are used for this inbound / outbound transfer. Is there something I am missing on CUCM or on the E1 interface to allow or force off-net transfers to release and not hairpin or tie up channels?
I am running CUCM 10.5.2 with MGCP control of my voice gateway.
Hey Jaime, I have been searching the forums for an answer to a question similar to this one, and I see you comment a lot on the posts, I was hoping I could ride on this thread instead of starting up a new basically duplicate thread.
With this Pandemic hitting, 90% of our workforce is teleworking. They want to forward their deskphones to a home phone. We run CUCM 11.5SU6 behind MGCP controlled T1 lines on our ISR 4431's. Is there a way to prevent hairpinning/tromboning calls that come in, hit CFWA and go back out the T1? You mentioned Telco support of TBCT here, and in another thread I think you mentioned you need H323 for TBCT, which we don't use.
Right now we are denying the forwarding as we only have 6 T1's for ~2,000 end users. If we can find a way to break off the calls if CUCM doesn't have to control them I'd be a happy camper
No, you can't do anything about this with MGCP.
Your telco needs to support TBCT, if they don't, no way to do this.
And that's a TCL script which doesn't work with MGCP.
