[OpenSIPS-Users] mid-registrar and WSS

[Esty, Ryan]

Hi opensips users,

I have a couple of questions and I'm hoping someone can point me in the right direction.

We have a SIP PBX that doesn't do WSS for example using sipml5. I'm trying to put opensips in the middle of the SIP PBX and the WSS client with limited success using mid-registrar in opensips 2.3. If I don't try to pass the registration through and just use opensips as my SIP server the WSS client will register and calls can be made. If I do put in the mid-registrar and pass through the registration to the SIP PBX the SIP PBX will register the phone and pass back the 200 OK the client gets a message back but doesn't think it is for him because I'm assuming it is missing the VIA. On a successful registration the client will see the VIA on the unsuccessful registration the client doesn't see the VIA.


My first question is am I using the mid-registrar as designed I'm trying to set it up as contact mirroring (mode 0)? If I did pick the correct method why is my VIA disappearing and can I get it back? Someone on the list mentioned this https://blog.opensips.org/2016/12/13/how-to-proxy-sip-registrations and I will try it soon but it seemed the mid-registrar which I don't think was released yet was supposed to automatically do this.

This is the debug output when the registration is failed:
