[OpenSIPS-Users] mid_registrar remove all bindings

Mon Jun 18 09:27:40 EDT 2018

Hello.

We have simple schema Phone -> OpenSIPS with mid_registrar -> Asterisk. And
there is strange process for REGISTER message from Phone with "*" in Contact
(remove all bindings).

After standard sequence with Authorization and receiving Ok from Asterisk,
mid_registar generates additional REGISTER message with sequence number of
first (Unauthorized register) message. Asterisk of course answers with
error. This message contains Contact:
<sip:2552 at 10.20.20.248:5060>;expires=0. But is it needed, if we already
removed all bindings, and got the answer, that they are removed?
