[SR-Users] Regex not capturing as required for subst_hf

[Salvinder Parhar]

Hi,

I'm trying to capture and substitute the host IP of contact header using
the subst_hf but it's not working as expected. I tested my regex in a
tester and it works fine there but not in Kamailio config.

*Regex:* @(.+?)>

*Substitution:* @PUBLIC_IP:5060>

*Three contact headers that I'm trying to match;*

Contact:<sip:0065*7766 at 199.48.100.166:5060
>;methods="INVITE,ACK,BYE,CANCEL,OPTIONS,INFO,MESSAGE,SUBSCRIBE,NOTIFY,PRACK,UPDATE,REFER"

Contact: <sip:0065*7788 at 172.16.1.216
;transport=udp>;expires=3600;reg-id=1;+sip.instance="<urn:uuid:03660bc5-bb70-4784-8ac5-000413B108BA>"

Contact: <sip:0925*0007 at 199.48.100.166:5060>

*Outcome I'm expecting for the three contact headers;*

Contact:<sip:0065*7766*@PUBLIC_IP:5060>*
;methods="INVITE,ACK,BYE,CANCEL,OPTIONS,INFO,MESSAGE,SUBSCRIBE,NOTIFY,PRACK,UPDATE,REFER"

Contact: <sip:0065*7788*@PUBLIC_IP:5060>*
;expires=3600;reg-id=1;+sip.instance="<urn:uuid:03660bc5-bb70-4784-8ac5-000413B108BA>"

Contact: <sip:0925*0007*@PUBLIC_IP:5060>*

This regex in Kamailio works fine for the first and third contact header
but for the second contact header it matches all the way to the end of the
contact header excluding the quote (") sign. I've tried so many other
combinations [like *@(.+?)>;?* ] of regex but nothing seems to work.

Is there a way to accomplish this with one regex?

Thanks,
Sal
