[OpenSIPS-Users] How to send 200 OK for REGISTER without adding Tag in SIP-To-Header (To-Tag $tt)

[Bogdan-Andrei Iancu]

Hi Pai,

It is a must (by RFC3261) to have a TO-tag in any final reply (including 
200 OK) . What are you asking is a violation of the SIP RFC.

I guess the problem is in the SIP client from the NOKIA device. You 
should try to solve it there.


Anyhow, to answer to your question, no, there is no way to send a 200 OK 
without To-tag :).

Regards,
Bogdan
