[Kamailio-Users] Contact field

[Alex Balashov]

I am not sure.  These are all nuances that differ among regex 
implementations.

Perhaps you need to escape the dots in the decimal IP notation, as they 
have a meaning in regex.  Perhaps the $ end-of-line will never be 
matched.  Different embedded regex implementations always work 
differently;  just have to massage it until it works.
