2021年7月6日 · The traffic between the IP Phone though and the SBC, at best, you can enable SRTP, but not SIP TLS (SBC does not listen for SIP TLS). Mind you, unless you are worried that there may be 'leaks' on the internal network, this should not be a problem because as mentioned, the traffic from/to the PBX is encrypted and that is what passes over the ...

2019年8月30日 · We are trying to enable SIP TLS and SRTP on Windows softphones. We are using custom FQDN. When switching extensions to SIP TLS, softphones can't register. We have tried both Digicert certificates and issued by domain CA, and both of them are trusted on Windows hosts. SIP TLS works well on Snom IP phones with these certificates.

2014年5月3日 · I know I can enable Secure SIP and Secure RTP in the phone provisioning tab on the extension by changing SIP transport to TLS and RTP mode to Only secure. For the SIP trunk, when I go to options, SRTP Mode should either be enabled or enforced and Transport Protocol should be TLS. But what about the TLS Root Certificate?

2020年11月6日 · Hello, We have trouble configuring TLS and SRTP on 3CX and Yealink T46S/G. Phones: TLS on the phones works but if we set SRTP to "Compulsory" it rings but we can not answer the phone. 3CX: If we enable TLS (in the SIP trunk) the entire SIP trunk stops working (with correct .pem file). I set...

2020年7月13日 · The best solution is "Direct SIP (STUN Remote)". The catch is that all SIP signaling and RTP audio is sent in the clear for anyone to intercept. It's trivial to create a custom template for Yealink T4x that sets the phone to use SIP over TLS (SIPS) and SRTP. What I would really like is built-in template support.

2020年5月15日 · This occurred as soon as the update to 16.0.612 was applied. Prior to 16.0.612, we were able to use Port 5061, TLS, and SRTP for our SIP Trunk provider without a problem. Please help, as we would prefer to use TLS and SRTP in our environment. Using IP is not an acceptable workaround because the TLS Root CA depends on a domain match. Thank you.

2019年8月1日 · Currently there is no official support for deskphones to use SRTP and we do not recommend it. It possible to do though, if you enable it in the extension, by the provisioning of the 3CX App (applies to whole extension). And then enter the phone UI you can change your SIP transport to TLS with port 5061*, and your media transport set to SRTP.

2023年6月27日 · Hiya, I've been having ongoing issues with trying to get Vodafone SIP going since the service went live over 2 weeks ago. Working alongside Vodafone's technicians we are getting close. UDP connection had no issues establishing but we need the secure TLS. From what we can tell, everything is...
