[Freeswitch-dev] Bug with variable_endpoint_disposition and Answer-State event parameters

[Mark Sobkow]

I tried changing the answer timeout to 2 seconds, but Freeswitch 
"originate" is definitely not honouring that request.  The originate 
command is:

originate, sofia/external/533 at rats.marketel '&erlang( pbx_called_cust 
pursuit at testsrv )' 5
