Hello,
if you have kamailio 5.2, you should enable ignore of sips in rr:
-
https://www.kamailio.org/docs/modules/stable/modules/rr.html#rr.p.ignore_si…
If you have an older version, just before use of record_route inside
kamailio.cfg, do:
if (uri=~"^sips:") {
$ru = "sip:" + $(ru{s.substr,5,0});
}
The presence of sips in r-uri of invite forces rr to set record-route
with sips, but this results in some UAs just clone the uri scheme, not
really understanding its purpose, anyhow, as already mentioned here,
sips is a mess over all, so disabling it is safer. That's why I started
to add options to kamailio to just ignore it.
Cheers,
Daniel

Hi Daniel,
Certainly, here is the sequence including INVITE and 200 OK. I note
that the Contact on the 200 OK doesn't mention TLS, but the
Record-Route header does.
Thank you.

Hello,
do you have the INVITE and the 200ok corresponding to this ACK? I
need to see the R-URI of INVITE as well as the contact in 200ok in
order to analyze why sips appears in ACK.
SIPS requirements are sort of a mess, probably the best would be
to let it for config to decide when to allow forwarding or not in
case of sips URI.
Cheers,
Daniel

Hello all,
We're having an issue with Kamailio not processing an ACK and
hope someone can help. A PCAP shows that Kamailio is receiving
the ACK, and we believe these log messages are directly related
to it:
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm
[ut.h:279]: uri2dst2(): ERROR: uri2dst: bad transport for sips uri: 1
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm
[t_fwd.c:1777]: t_forward_nonack(): ERROR: t_forward_nonack:
failure to add branches
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: sl
[sl_funcs.c:387]: sl_reply_error(): ERROR: sl_reply_error used:
Unresolvable destination (478/SL)
The ACK is as follows. It's from telephone 111111 which is using
TLS, which Kamailio listens for on port 5061.
Does anyone know which URI has the bad transport as per the error
above? Might it be the From URI "sips:111111@es8.example.com
<mailto:sips%3A111111@es8.example.com>" because it doesn't
specify port 5061?
Thank you in advance.
