Hello List , Good Morning. In my fight to get ESL & Python & Freeswitch all to behave properly i noticed a possible BUG ( need the veterans to confirm). Scenario : Originate & ValetPark () + MOH OR Just Park() , Both show the same problem. Codec G729 I Make another call: originate & park() codec G729 Now Python ESL Inbound Or FS Console : uuid_bridge uuid1 uuid2 +OK uuid Now one of the two things happen : 1) One the call gets connected hurray :) , Audio Perfect , etc. 2) The call gets dropped :( In both cases uuid_bridge reports +OK even in the case the call is dropped. Even if i Park() Both Calls using the dialplan XML ( NO ESL with those SYN/ASYNC Problems) I still get sometimes ( not always) a dropped call could this be related to the use of G729 ? I have lots of available licenses. Regards António Teixeira
