[Freeswitch-users] how to add to sip To/Contact/Invite uri on outbound call?

Is there any way to add a parameter to the outbound uri via dialplan variables? In particular, I'm wanting to investigate setting a 'tgrp' and 'trunk-context' value on some outbound calls. http://www.markholloway.com/blog/?p=352 -- Nathan ------------------------------------------------------------ Nathan Neulinger nneul@mst.edu Missouri S&T Information Technology (573) 612-1412 System Administrator - Architect
