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.
