Hi,<div><br></div><div>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.</div>
<div><br></div><div>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.</div>

quick question to double check if what I understood when I read the specs<br>
was ok -- in gruu/ob, it does not matter anymore the callid/cseq<br>
combination, or there should still be some checks related to it?<br>

In fact that depends on Outbound instead of GRUU, and not, when using<br>
Outbound the registrar does NOT check the Call-ID and CSeq of the<br>
REGISTER (and using GRUU means that Outbound is also used, so the<br>
Contact has a +sip.instance and reg-id params which are inspected by<br>
the registrar to create/update/delete a binding).<br>

but what about same callid with lower cseq, combined with same sip instance and reg-id?<div class="HOEnZb"><div class="h5"><br>
