Comparison of SIP-Based Features and MGCP-Based Features
Distinctive Ringing Call
Waiting
DRCW Provisioning for SIP does not differ from provisioning for MGCP. However,
the delivery method for DRCW is different.
The subscriber provisions a list of DNs to receive DRCW tones.
In MGCP, the phone plays the tone specified by the CiscoBTS 10200 in the
protocol message. In SIP, the tone provisioned for the DN is specified by the
Cisco BTS 10200 in the Alert-Info header of the INVITE as a file URL. A SIP
phone, if capable, can interpret this header and play the specified distinctive
ringing or call-waiting tone.
