CUCM T1/E1 Hairpin

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.

 

Thanks

Re: CUCM T1/E1 Hairpin

This is how it works in CUCM (unlike call forward). CUCM will accept call
one, establish call two then hairpin the call legs on the voice gateway.
This is important for call billing (caller#1 pays for first call and
transferor pays for second call).
