[SR-Users] Problem with TLS

[Arik Halperin]

Daniel, Thank you!

You are right about this.

I configured PJSIP not to check whether the contact contains SIPS.

This solved the problem on one of my setups where I have one NIC that has a public IP.

However on the original setup, the kamailio has one public IP and one private IP. In that setup, the ACK to the 200 OK is not forwarded over the private IP to the freeswitch. This only happens in TLS, when I work with TCP it works well. I believe it is somehow connected to the record route, and I’m looking into PJSIP to try to find the answer, but is there anything I could do in the kamailio?

I have the same problems with other SIP clients(Bria for example)


Thanks,
Arik Halperin

Hello,

Kamailio is not involved in the issue reported here. Practically, pjsip expects sips: scheme in the contact URI, which was set by FreeSwitch in 200ok. Maybe there is an option that you have to turn on for FreeSwitch to use sips: scheme.

Otherwise, you can try to replace sip with sips in kamailio config and do the reverse the other way.

Cheers,
Daniel

PJSIP responds with:

Secure dialog requires SIPS scheme in Contact and Record-Route headers, ending the session

What is the reason for this? How can I fix this issue?

Thanks,
