[Freeswitch-users] Remote audio not heard

[I put the Who? in Mishehu]

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.
