Hi all,
I have a question about MSRP client ports binding.
I have two clients used in the IMS context (SIP signaling before setting up
MSRP connections). The first client(UE1) send an INVITE to the second

1) to forcibly *unregister* a device. For instance, you have a device
registered from work, and then you go home without turning it off.
From another suitable device at home you can unregister the device
at work. Of course you may have to keep doing
Agree there is no generic behavior here. IMO, if there are multiple UAs
registered to the same AOR, then one should be able to call the AOR and
reach the others. If a UA initiates an INVITE and receives that invite
itself, in many cases it should probably reject that, because it is
busy. It can

Hi, I think I already was replied to a similar question but
unfortunatelly I don't find it.
The question is: when/where is useful sending a REGISTER with a
