[SR-Users] Kamailio 5.2.2 ICSCF changing sip to tel

[Woscek, Martin W.]

Hello all,

The HSS is responding with 604 errors when the I-CSCF checks the public identity of the caller.  PCAP attached.

It looks like our I-CSCF is modifying the sip uri's to tel uri's (e.164-like), referenced attached PCAP:
in_uri=sip:alice at ims522.irisims.org
out_uri=sip:+alice at ims522.irisims.org

syslog output:
Jun  6 16:50:06 imskamailio /usr/local/sbin/kamailio[14066]: ERROR: <script>: $ru => sip:+alice at irisims.org

Looking at the default (out of the box) Kamailio.cfg for I-CSCF the following script snipet is where the modification to our sip URI is happening:

# -------------------------  request routing logic -------------------
# main routing logic

route{
#!ifdef WITH_DEBUG
                xlog("I-CSCF >>>>>>>>>>>>>>>>>>>> $rm $ru ($fu => $tu ($si:$sp) to $tu, $ci)\n");
#!endif

                if !($rU =~ "\+.*") {
                                prefix("+");
                }

Is there a I-CSCF setting directive we missed?
Or should we simply comment the above?

Any advice is appreciated.


Thanks,
Martin Woscek
