I have a specific question relating to CallManager when integrating over a SIP Trunk. Does anyone know if the Sip-UA within CallManager supports SIP registration? I have a specific scenario where a SIP Service Provider requires CallManager to maintain an active SIP registration in order to direct calls to inbound. I know this feature is supported in IOS.
SIP trunk registration is not supported in CCM. You need an IOS IPIP gateway to do this.
There are no plans to implement this.
