[OpenSIPS-Users] How to change Contact header

[Bogdan-Andrei Iancu]

Hi David,

take when using such regexps as the contact hdr may have multiple syntaxes:
    Contact: sip:user at domain
    Contact: sip:user at domain;hdr_params
    Contact: <sip:user at domain>;hdr_params
    Contact: <sip:user at domain;uri_params>;hdr_params
    Contact: "display" <sip:user at domain>;hdr_params
    Contact: display <sip:user at domain>;hdr_params

    etc....

So having a regexp to match all case may be difficult....better try to 
focus only on the domain part, like matching the "@IP" part...., like
    (Contact: .*@)[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}

Regards,
Bogdan
