If you're trying to modify the contact on your branch I believe you need to
do that in a branch route. For example in branch_route[EVAPIRESPONSE] you
could modify the contact header and. Just make sure to set the branch route
in route[EVAPIRESPONSE].
Then instead of using a var you could use an avp. avp's work as a stack so
a single avp could hold all of your contacts. In your branch route you
could then do something like:
remove_hf('Contact');
append_hf('Contact: $avp(contact)');
pv_unset ("$avp(contact)"); # This will pop the first contact off the avp
so the next time you call this avp you'll get the second contact
I hope that's helpful and gives you some ideas.
