Can’t transfer calls back through Cisco NI2 connection.

[Frav82]

We have a NI2 connection between our 4K V7 and corporate s Cisco CUCM 12.5. Corporate accidentally ported our Main Line to their AT&T SIP. Calls still reached our Operator through the NI2 connection however, when the Operator tries to transfer a caller back through the NI2 connection to one of our Cisco phones it does not allow the transfer. The temporary workaround was to point our Main Line in Cisco to another DID that wasn’t being ported, and through DNIT send it to the Operator. The Operators are once again able to transfer callers to our Cisco phones through the NI2 connection. I’d like to give calls coming in through our NI2 connection the ability to be transferred back through the NI2 connection if needed however I’m not sure what what I’m missing.
