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
