Twilio TLS

[herbertshades]

Has anyone been able to connect ProSBC to Twilio via tls. Plain SIP on port 5060 works. Getting tls to work per instructions on
https://docs.telcobridges.com/tbwiki/Create_A_SIP_Certificate_A and on youtube, I just can't get calls to work inbound into ProSBC.

Does anyone have this working?

Hi

Please try disabling Require peer authentication option under the TLS Profile. You can use tbsigtrace capture to check the traffic between your sbc and Twilio.

tbsigtrace shows that the calls are coming in from Twilio into port 5061, from random ports. I don't think that is a problem however. ProSBC responds with a 100 Trying then with a 488 Not Acceptable Here and Twilio ACKs that 488. The IP addresses are all good in the Access Control List.

I have another provider that is coming in on port 5061 (tls), from random ports, and those calls work just fine. Same TLS Profile, with disabled Require Peer Authentication.
