While calling certain destination phone numbers (via freeswitch-1.4.7, and flowroute), often, on the calling devices (SPA942, SPA942, GrandStream, old phone on SPA3102 ATA), no ringing is heard and, though the destination has answered, no audio returns from the destination (although destination can hear audio from caller). The same destination numbers sometimes work correctly and sometimes fail as above. Logs show normal activity, meaning no difference between normal and fail. Exact same thing happened on freeswitch-1.2.something, 1.4.6, and now 1.4.7. Exact same thing happens across wildly different calling phones, across many different destination numbers. Just about the only thing that has not been changed, updated, etc. is flowroute as the carrier. Could it be a problem at the flowroute end? Anyone else having similar experiences? Any ideas on where to begin? TIA, Michael
Are you getting silent rtp or no rtp? from fs_cli "sofia global siptrace on" Also get a tcpdump of both legs and analyse with wireshark. On Sat, Aug 23, 2014 at 1:21 PM, Michael <mike@brenden.com> wrote:

Michael, Do as Russell recommends, but I will tell you that I do indeed experience these issues specifically with Flowroute. Whenever I look at the rtp, I only see it flowing in one direction though the SIP negotiation appears to have worked fine. It's been very hard for me to track down the root cause as I barely make any calls through that account anymore... Let us know if you are seeing the same thing, what codecs are being negotiated, what your ISP is, and what is the c= line on the SDP that comes back from Flowroute on the 200 OK. -- Yossi Neiman On 08/23/2014 12:45 PM, Russell Treleaven wrote:
