Ali,

With the exception of a few, pseudovariables that expose parts of a SIP message (such as $ct) are read-only, so you cannot assign values to them.

Why are you manipulating the Contact header? This is not something proxies should ordinarily do.

But, assuming you really want to/know what you're doing:

‎remove_hf("Contact");

append_hf("Contact: <sip:...>\r\n");
