Hello,

that prefix operation is done only if the r-uri username does not have +. So if you HSS is returning the r-uri with +, then all is ok, no other + is added.

On the other hand, I am not sure what is the error or the issue you try to sort out. The error message is because of the xlog(...) in the config.

Cheers,
Daniel

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
