[cisco-voip] Cisco ATA187 and Valcom 9940

[David Ellison]

dip 1 turns on the forced timeout feature, dip 5 sets it to 16 seconds
maximum page.

 

You could try setting dip 1 Off, dip 7 and 8 On.   That will enable Audio
Sense with a 4 second silence detection.  If that is too long, and the
reorder tone still comes on before the V-9940 disconnects, change dip 7 to
Off and dip 2 to On.  That will drop the Audio Sense to 1 second.

A few cautions, though.  If you change the V-9940 to Audio Sense and the
reorder tone starts, the V-9940 will never hang up and you will have to
disconnect the tip/ring or power to make it stop.  A noisy analog line could
also be enough to keep the unit active.  Also, if the caller pauses speaking
longer than the timeout, the 9940 will disconnect.

 

I don't know what the difference is between the ATA186 and ATA187, except as
a previous response indicated the ATA187 doesn't appear to provide a good
loop disconnect at the end of the call.

I had dip 1, 5 and 8 on.

 

If I was making a 17 second page, it will hang up on me at 16 seconds.

 

If I make a 6 second page, it begins a reorder tone about 3 seconds after
the ip phone has hung up until 16 seconds, then it hangs up the call.

 

This is how I have been setting up a 9940 for a long time with an ATA186
with stock configuration. (no fancy tweaks)

 

Keeping everything the same, I swap out to an ata187, it doesn't work. I'm
sure theres something that has to change..... just what it is.....?

When the phone call disconnects, is there any time between the end of the
page and the start of the reorder tone?  The V-9940 has the ability to
disconnect on silence.  The shortest period of silence it can detect is 1
second, but that also means it may hang up too soon if the caller pauses
during the page.  Four seconds is the next shortest interval that can be
selected. 

The change is made using dip switches on the V-9940.  The switch settings
can be found in the installation manual for the V-9940, available at
