Hi
Quick update...
I switched the CPE from TLS to TCP
Now the CPE registers with sip: and ;transport=tcp
The problem does not occur.
I attemted to reproduce the issue with a CPE using sip: ;transport=tls
The problem does not occur.
I fear, something goes wrong kamailio internally if the sips: scheme is being used.
Mit freundlichen Grüssen
