[Freeswitch-users] One-way audio on first leg of attended transfer

[Richard-Freeswitch]

I'm experiencing one-way audio on the first leg of an attended transfer. 
  The originator of the transfer hears audio but the destination user 
does not.

The one clue I have so far:  the FS log shows a PGRES_FATAL_ERROR and 
the Postgresql log says 'ERROR:  duplicate key value violates unique 
constraint "calls_pkey"', and the channels record update also fails as a 
result of the calls update failure.

Any ideas on the cause of this issue?  Log lines from fs_cli are pasted 
below.

Thanks!
