wtatx,
Like most phone systems the MiVO-250 is run by timers and in this case there are a few timers, one in particular, that is causing this to happen.
When a call is put on hold at a station the Hold Timer [Default: 60 sec] or Alternate Hold Timer [Default: 180 sec], which ever one is set for the phone, is enacted. After the Hold Timer has completed its count down then the Recall Timer [Default: 60 sec] is enacted. If the person doesn't pick up the call by the time the Recall Timer is up then the call will go to the Recall destination; which is the Attendant. If no one has touched the timers then it 120 seconds or 2 minutes before it Recalls away from the phone. Also, when the Recall Timer is up the Abandoned Call Timer is enacted so if there isn't an Attendant programmed for the phone the call will be disconnected when the Abandoned Call Timer is up.
To fix your problem you need to know which Hold Timer they are using which is easy enough, but it is on a per phone basis so make sure you know which one to set.
Go to System > Phone Related Information > Flags > Alternate Hold Timer: see if there are any phones showing up under this flag. If there are not any phones located within this section then all phones are using the standard Hold Timer by default.
If you don't want all phones to follow the Hold fix then just set any phones they want under the Alternate Hold Timer and adjust that one for your fix; also the Alternate Hold timer has a larger adjustable setting.
So, the Hold and Alternate Hold timers can be found here: System > Timers and Limits > Hold or Hold - Alternate
Hold Timer: 0 - 255 seconds or 0 = Indefinite to 255 = 4 minutes and 15 seconds
Hold - Alternate Timer: 0 = indefinite to 1000 seconds = 16 minutes and 40 seconds
So, just adjust the timer to their satisfaction and you will be their new hero.
Thanks,
TE
