remove tls in from and to fields

[Grace Liu]

After the sip trunk is using TLS to register successfully, we cannot call out through the sip trunk, the sip trunk provider replys that it is because of the tls protocol added in the from and to fields, how can we remove this tls, do you have any suggestions?

try to using udp on your siptrunk profile, and also try to test call using 3cx webclient

After we use UDP and RTP, the sip trunk will fail to register:




Thanks

Ohh i see, set to tls again, test call using webclient, if you receive error code, escalate to your sip trunk provider, i think if status registered, you can get the sip error code response from your sip trunk provider.

Yes, thanks for your suggestions, and we have consulted the sip trunk provider, they want us to remove the tls in the from and to fields of the registration request and the invite request.
