I've been reading the freeswitch book (great read!) and playing with my first freeswitch install on a Mac mini host with freeswitch installed via git into a Virtualbox guest CentOS 6.4. It's working with a couple X-Lite softphones and a Yealink T32G, internally between extensions, using a free DID to test incoming calls and a free but limited iptel account to test outbound. My next step was to try and play with real outbound calls so I followed these instructions for Google voice: <http://wiki.freeswitch.org/wiki/Google_Voice> but outbound calls fail and are hung up. I disabled the h264 codec in dingaling.conf.xml leaving just PCMU but no change. xmpp appears to be connecting and authenticating to google correctly. The log of an attempted call (edited for privacy) is at <http://pastebin.freeswitch.org/21338> Snippets of the log that looks suspicious to a freeswitch noob: 2013-08-26 20:45:33.568012 [DEBUG] mod_dingaling.c:1627 Accepted 0 of 0 rtp candidates. 2013-08-26 20:45:33.568012 [DEBUG] mod_dingaling.c:1629 Accepted 0 of 0 rtcp candidates. 2013-08-26 20:45:33.568012 [DEBUG] mod_dingaling.c:1632 Accepted 0 of 0 video_rtp candidates 2013-08-26 20:45:33.568012 [DEBUG] mod_dingaling.c:1635 Accepted 0 of 0 video_rctp candidates 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:4114 using Existing session for 2155444888 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3577 3 rtp candidates 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3597 candidate 74.125.141.127:19305 PASS ACL wan.auto 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3651 Acceptable rtp Candidate 74.125.141.127:19305 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3577 0 video_rtp candidates 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3577 0 rtcp candidates 2013-08-26 20:45:34.649239 [DEBUG] mod_dingaling.c:3577 0 video_rtcp candidates 2013-08-26 20:45:35.208090 [DEBUG] mod_dingaling.c:4114 using Existing session for 2155444888 2013-08-26 20:45:35.208090 [DEBUG] mod_dingaling.c:4434 hungup dingaling/gtalk/+7609876543@voice.google.com Where should I be looking to try and fix? Freeswitch is behind the firewall with a private IP but STUN says it's working (or at least it looks that way to me). Thanks, -Terry
