    [ https://issues.asterisk.org/jira/browse/ASTERISK-24602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=227370#comment-227370 ] 

cervajs commented on ASTERISK-24602:
------------------------------------

this debug shows that TLS transport is chosen, but transport=wss is configured for endpoint

contact webrtc_cervenka/sips:webrtc_cervenka at 1.1.1.1:58757;transport=wss;rtcweb-breaker=no

can i change somehow pjsip resolve transport?

> Calls to WebRTC client (sipml5) via WSS transport or chan_pjsip always fail.
> Registration and calls from WebRTC client work without issues.
> I believe that the issue is about Asterisk trying to use wrong transport (TLS instead of WSS) to SIP INVITE WebRTC clients.
> Error summary:
> 1. TLS transport isn't configured in pjsip.conf:
