Hi, I have a question here:
For several ISDN subscribers under one NT, How they register to SIP Server I think: 1. For each ISDN subscriber, register message should be like several To URL with its unique contact URL, which means several logic SIP/TEL URL now bind with the physical eqquipment(Phone or PC or else) 2. If those ISDN subscribers share the same default telephone number. now a phone outside calls the number(ISDN subscribers are callee), is it possible to distinguish them or not from caller side? I hear of sub-address may be used? how to use it? Thanks If you share me the call flow, That will be more helpful. _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [email protected] for questions on current sip Use [email protected] for new developments on the application of sip
