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-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
