IPO 400 issues with analog ports staying open after disconnect 1

[Webnx]

we have IPO 400, our inbound lines come in on a t1. we have a 30 port digital add-on for most of our extensions, but we also have a 16 port analog box for our automated dispatch system. it has 6 analog lines in a hunt group. it works fine / answers and transfers calls fine. however we have a problem when a user hangs up while on the analog port, the port stays open. the maker of the system EFI / ADS, they say we need "disconnect supervision". we tried a few different things and the system still does not see the port close when people hang up. any ideas? anything I can look into? the ports are setup as "analog phone" we tried IVR w/o any luck.

so far the only option given to us by the company that installed the IPO, get another 16 port module, a trunk module, get 6 analog phone lines from the phone company, and have those route over to ads. they say the analog lines will give the disconnect supervision that the t1 cannot give.


Thanks for your time!

Set your extension ID as IVR Port.

IVR Port: Provides a disconnect clear signal to the attached device at the end of calls. This is required by some third party devices. When selected the Disconnect Pulse Width is displayed and can be adjusted if necessary. Note: This feature is only configurable when the locale setting is configured for enu .

Sounds like the devices are expecting the disconnect signals that an analogue line would provide as u state. Probably need to test the trunk module to confirm this, 1 line and a 4 port analogue card is all u need to test

I ran into this same problem. We are using Telos equipment hooked up to 10 analog lines in a hunt group. Our lines also come in over a T1. When a caller hangs up the line stays open. This only happens after the line has been answered. I haven't tried this yet but was told by the engineer at Telos to look into a CPC generator that passes through the disconnect signal. He pointed me to sandman.com catalog page 94. Some more information about it is at sandman.com/cpcbull.html

I was able to correct this today. I changed the port type to IVR and changed the "disconnect ??? " the option that pops up after you change the port to IRV to 32ms (the max) I found out later most devices need atleast 150ms, and the default time out is 10ms. btw 32ms = 320 ms, as its 10ms units, so the default was 100ms which was not enough, and the ADS system was never able see the call dropped
