I am trying to modify Contact: sip:8133740008@1.1.1.1;transport=udp;maddr=1.1.1.1

to Contact: sip:8133740008@2.2.2.2;transport=udp;maddr=2.2.2.2

I am using the following statement but it doesn't work: if ( subst('/^Contact:(.*)sip:[^@]*@([a-zA-Z0-9.]+);(.*)$/contact:\12.2.2.2;\2/ig') ) {};

Am I missing anything?

Thanks, Alex

The various NAT traversal modules modify the Contact to suit their ends, according to their own scheme.

There is a module that will allow you to modify any header to anything you want:

Hi,

Is there a function that can modify "Contact" field in SIP header?

Thanks, Alex

Here is a reference site about regular expressions: http://www.regular-expressions.info/

subst() uses POSIX compliat regexp.

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.
