I have the following questions about conveying carrier identitification code in SIP.
On the ISUP side we get three information 1. Type of network identification 2. Network identification plan(3 digits or 4 digits) 3. Digits 1-3 or 1-4 Q1. The draft draft-yu-tel-url-08.txt provides a mechanism to convey the digit information on the sip network. However how do we convey the type of network identification information on the SIP network. Q2. On a UAS receiving an INVITE message with cic=+11234 or cic=1234, what is the difference between the two cic information. Does this mean something different needs to be conveyed on the ISUP side.
