Secondly: Asterisk uses a different Call-ID for each registration.
RFC3261, section 10.2 (Constructing the REGISTER Request) says:
Call-ID: All registrations from a UAC SHOULD use the same Call-ID
header field value for registrations sent to a particular
registrar.
If the same client were to use different Call-ID values, a
registrar could not detect whether a delayed REGISTER request
might have arrived out of order.
OK - so its a SHOULD not a MUST. And I can't say I understand the
reasoning. But I adjusted chan_sip to keep the same Call-ID for all
REGISTERs to a particular registry and that fixed my remaining
problems with incoming calls nicely.
In any case, it improves our compliance with the RFC, and its a very
tiny patch (half the code seemed to be there already, anyway).
Okay so I applied it but does that also mean our seqnos need to increase
forever?
