Hi all,
We had to connect to an SBC, which was not compliant to RFC 3261.
It was urgent, because management was waiting for first call.
Within minutes, I could implement a workaround in kamailio routing configuration:
## CV experimental 2022-02-17: fake Supported HF
if (is_present_hf("Require") &&
!is_present_hf("Supported")) {
append_hf("Supported: $hdr(Require)\r\n", "Require");
msg_apply_changes();
}
Thank you, kamailio!
All the best
Christoph
