Hello all, I'm going on the fourth day with no response from icall's support on this issue, so I would greatly appreciate any guidance. Freeswitch successfully registers with icalls outbound server, sbc01-car.dal.us.icall.net, and incoming calls are handled properly. But when I try to call a land-line with pa call 1813968XXXX, I get a response of 480 Temporarily Unavailable. I've also registered my external ip address with icalls servers. Also, this works "originate sofia/internal/9996@conference.freeswitch.org 1000", but this doesn't "originate sofia/internal/1813968XXXX@sbc01-car.dal.us.icall.net:5060 1000."
