When I do a attendant transfer (default *#) there is a time when the PBX is trying to connect to the called number. I guess that the time is set by the variable atxfernoanswertimeout (default 15 sec). I have changed the atxfernoanswertimeout variable from 15 seconds to 80 seconds and restarted the PBX. But when i do an attendant transfer it still sends the call back after 15 seconds not 80 seconds.
I do an attendant transfer by pressing *# extension # then I hang upp my call so the call is transferred directly to receiving end.
