greetings, I have a customer that is sending the REGISTER with 2 ports in the Contact
header:
Contact: <sip:44435661000448181@201.xxx.xxx.xxx:19778:5060>
After some troubleshooting we found that the wireless router is the one inserting the 2nd
port. It is not the SIP UA itself. Is it possible to "sanitize" the REGISTER at
the beginning of the configuration logic with the TEXTOPS module so that we can leave one
port and then process the REGISTERwith the typical: if (!www_authorize("$fd",
"subscriber")){...} Or will this only applies to messages that are
proxied/forwarded (example: received malformed INVITE, before calling route[1] to send it
to the destination sanitize it with the TEXTOPS functions)I guess my question is: after
removing the extra port at the begining, when I call the "if
(!www_authorize("$fd", "subscriber"))",will it process the
modified version or the original one? txs a lot fborot

Hi,
Look at this function from the textopsx module
http://kamailio.org/docs/modules/stable/modules/textopsx.html#msg_apply_cha…
Try to apply it after your sanitize and before you challenge the REGISTER.

Txs a lot Reda, I will try it
Although I made a couple of test w/o it and so far it looks like the modified message is
used on the next processing , not the original one but I will keep testing

Maybe there is special handling for Contact header, because IIRC,
fix_nated_contact() before save() also works.
