Hello everyone,

I’m trying to get the host part from the contact header in the sip invite packet.

Following is the contact header format:

Contact: <sip:user_name@192.168.1.1:5060>

What I want as result is 192.168.1.1

I searched among the pseudovairables  and found $ct variable which reference to the body of contact header. (<sip:user_name@192.168.1.1:5060>)

Is there a way to get directly the host (192.168.1.1) without applying transformation at the level of $ct.

If not what transformation can achieve it.

Thanks in advance.

Regards,

Ali
