Running Unity 3.1.6 with an Avaya G3R 9.5 PBX integration. Selecting phone playback from viewmail. When phone rings and it is answered you must wait 10 seconds for the message playback to start. If you talk into the receiver, it starts playing back the message immediately. Any idea where the setting is to change the 10 seconds of silence?
This is due to the lack of positive answer supervision on the analog line. Unity does not want to start playing the prompt BEFORE you answer the phone so it waits until the Dialogic board can determine the call has been answered. The board does do VAD (voice activity detection) and this is why playback can start as soon as you talk into the receiver. If VAD fails (i.e. you don't talk) then the Dialogic board must rely on detecting a break in the ringback cadence. Ringback cycles are quite long and to be safe about avoiding false positives the board is configured to wait up to 10 seconds between rings (leading edge) before declaring a connected state.
Setting is in the switch file, MaxWaitBetweenRings. It can be access through the Edit Switch utility also. I believe a standard US ringback tone cycle is about 6 seconds so you'll definitely want to stay above that. We've had it set at 10 seconds for many years now and have not done any testing to predict what all might be impacted. I do know serial integrations and Unity failover are particularly sensitive to this parameter on incoming calls.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
