@contact is the value of contact header field of the SIP msg being

If you need a static value instead, than put there a static value :)
Hi Lada,
if SER generates the response:
append_to_reply("Contact: sip:user@host;param=value\r\n");
if SER forwards the response:
(There might be a better way, the following example replaces the whole
header field. And I am not sure that it works correctly with multiple
contact headers.)
assign_hf_value("Contact", "%@contact;param=value");
Where is
the %@contact taken from? Let's say I will always use the same
SIP URI there. Will the param=value be included in following INVITE
sent from the
client somehow?
The UA parse the Contact in 302 and place it to Request-URI of new
INVITE but where the param=value will be?
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", "<%(a)contact.uri;param=value>")value>");
But you loose the header parameters this way :(
