    How to configure CUCM with SIP i-Protocol


      Dear All


      Our office have fiber optic connection from one ISP and the whole reason to contract this ISP is that they offer SIP trunking while other ISP could not at the time of procurement.

      When we checked with them about their SIP trunking service, they said only SIP i version or i protocol  are supported. I am not sure whether our CUCM could support SIP- i Protocol. How can we check before we contract for their sip trunking service?
