In the expert settings of sipml5 it says that disabling RTCWeb Breaker should make it compatible with softphones which are not implementing SRTP, that's how I have been testing it though. May I ask what attribute you looked at to get to the conclusion you have ?

<p>Hello,</p>
<p>can you get the SIP INVITE content that was received by the
endpoint returning 488? Maybe we can spot if there is something
wrong in the sip message content or an issue in the endpoint
software. Maybe it doesn't like headers with random string instead
of ip addresses (e.g., in via, contact ...).<br>
</p>
<p>I am not aware of any ims softphone with webrtc capabilities.<br>
