Hello all! I have a question. In my system we use a series of VoIP providers to receive external calls to our telephone numbers, for the same provider we have several registered numbers and we need our providers to send that information in some way, so far it does not seem that there is a common way to do it (report the number that was dialed by the person who made the call). From what I understand, SIP does not have a place for that information because there are no things like phone numbers in the specification, my question is, is there a correct place to send such information, or is it entirely up to each provider? (Now, the most common is to have in the RURI and To header, the id of the trunk registered in the uacreg table) I have seen a couple of options that seem to me the most “correct”: send the information in the To header or send in a custom header.
I really appreciate any help you can provide.

The proper place is the user part of the Request URI (R-URI).

Yes, I just learned that the Register method is not appropriate for registering several "numbers" in just one trunk. Still need to learn a lot.
Olle, thank you, I'm going to read it.
