In the INVITE the "Contact" field looks like this: Contact: <sip:XXYYZZ@11.22.33.44:5061;transport=TLS> How to reconfigure Asterisk, or where in the source code to make a change, so that the "Contact" always use FQDN =ast.firma.org and looked like this: Contact: <sip:xxy...@ast.firma.org:5061;transport=TLS> ?
