    Hi there, Does anyone know where the (TTS) Time-to-service feature gets enable in Communication Manager?

    I found this whitepaper that describes the feature and indicates it's on by default:

     

    https://avaya.dwalin.ru/wp-content/uploads/2010/04/Time-To-Service-White-Paper.pdf

     

    My experience reflects the behavior when it's enabled and I've never had cause to disable it.  Are you wanting to disable the feature?  I believe one "advantage" the feature has is to avoid CM overwhelm during network disruption recovery.  It does this by allowing CM to re-establish the TCP session to the phone instead of the other way around.  This allows CM to pace the connection recovery.

    Scott,

    Time-to-Service (TTS) refers to an architectural change made to H.323 phones in CM 4.0.  The idea was to speed up how quickly phones would be in service after an outage of CM (or back then a CLAN). 

    I'm not aware of any timers that drive this behavior.  Further, I don't see any benefit to disabling this feature.

    Thanks very much, I am not looking to disable it, I was hoping it would fix an issue I am having with DMCC service in AES. When I busy out and release a station the DMCC device goes to an idle state and does not come back to a registered state unless we re-instate the connected board in the Eventide Logger.

    Sounds like maybe Eventide doesn't support TTS mode.  You could try changing the Service Link Mode on the station to "permanent".   If the call recording stations are in their own network region, you could also try setting "Near End Establishes TCP Signaling Socket" on the ip-network-region to 'n'.    The behavior you describe is somewhat what I'd expect anyway.  Busy/Release of an H323 message sends an unregister message to the endpoint.   The Avaya phones reboot but non-Avaya endpoints might just stay unregistered.  Possibly there's a recovery setting in the Eventide software?

    Thanks, I don't see the Service Link Mode on the station form, what page is it on?
