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@ims522.irisims.org out_uri=sip:+alice@ims522.irisims.org
syslog output: Jun 6 16:50:06 imskamailio /usr/local/sbin/kamailio[14066]: ERROR: <script>: $ru => sip:+alice@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
