Distinctive external and internal ringing

[John Clark]

Is external ringing supported on transfered or forwarded calls? The scenario is that all calls come into Unty AA. Calls are then blind transfered to the extensions. The users want to distiguish between internal and external calls. Right now, the CID shows external number but only get internal ringing.

Distinctive Ringing is a feature that has been available from Cisco CallManager 3.0 when you use Skinny Gateways such as the DT24+ or the 6608 T-1 blade. However, this functionality is not available until release 3.1.2c with use of an H.323 gateway. In order to enable Distinctive Ringing, you must set the service parameter H323NetworkLocationOffNet to True.

I have a MGCP gateway with CUCM 5.1.2b. I assume this is also supported as a feature. But is the distinctive ringing extended once the call is transfered by another phone?
