@contact is the value of contact header field of the SIP msg being 
processed. So if you put assign_hf_value into onreply_route, than it 
returns the contact HF of the reply.

If you need a static value instead, than put there a static value :)

Oh, I see. Than you have to make sure that the parameter you insert is a 
URI parameter and not a header parameter, so it must be within <>. And 
you have to get only the URI of the original contact header field, not 
the whole HF value (if you do not use a static value), because the URI 
may have been already enclosed in <>:

assign_hf_value("Contact", "<%@contact.uri;param=value>");

But you loose the header parameters this way :(
