Hi My setup is Internet -> firewall -> asteriskbox -> spa3102a -> spa3102b the spa's can talk to the firewall directly. The firewall does NAT. The current asterisk flow for outgoing calls is phone => spa3102 => asterisk => vsp and vis versa for inbound calls. can I use re invite for outbound calls such that the spa3102 ends up talking directly to the vsp, i believe the firewall will handle it properly. But I am guessing i can reinvite on the inbound because all my 5060 traffic goes back to the asterisk server. So the question is on the sip.conf [context for spa3102a], can I put reinvite here and if not where can i put it.
