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

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

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.

Here is a reference site about regular expressions:
http://www.regular-expressions.info/
subst() uses POSIX compliat regexp.
Cheers,
