Re: [SR-Users] [sr-dev] Outbound and Registrar. No binding update

Hi, Outbound provides the UAC a way to update a binding even if it reboots. For that, a unique and permanent value of instance-id is used, which in conjunction with the AoR and reg-id determines the binding to the UAC. Having said this, I guess that the CSeq comparison between the one in the Register request and the one in the binding does not apply in this scenario since it is not guaranteed that a UAC saves the CSeq value of the registration among reboots.

In fact that depends on Outbound instead of GRUU, and not, when using Outbound the registrar does NOT check the Call-ID and CSeq of the REGISTER (and using GRUU means that Outbound is also used, so the Contact has a +sip.instance and reg-id params which are inspected by the registrar to create/update/delete a binding). but what about same callid with lower cseq, combined with same sip instance and reg-id?
