Partner ACS rel 3.1 (disconnect signal)

[pabell]

*We have a Partner with rel 3.1 Acs processor and a
couple of others 308 boards in 5 slot carrier
using the 4 port mailbox partner card ....

*so far we have replaced MAIN 308 as well as
the voicemail card because we can not get calls
to disconnect from voicemail once the user hangs
up .....calls continue to flow through to operator
as dead air / hang ups ...we have changed the disconnect
timer and dropped down to 50 from default of 450
dropping by 50 each time .....they are Centrex trunks
the carrier says its not them because they make calls
to a buttset while on site and calls do drop ...if you hangup from a call while on the partner phone but not in voicemail it does in fact drop off as it should just not
while in voicemail ( FYI all calls on centrex this is why we changed the processor first thinking it can not be an issue with all the cards...then changed the Voicemail card
next ...the carrier has a DMS 100 switch in this neck of the woods switch not a 5ESS as we see most .....trying to get them to change the disconnect signal is close
to impossible are there any devices we could use to "meter"
what we are getting for a disconnect ...go to a different site meter that out and compare apples to oranges and at least have something to throw back to them

Thanks !

has a CPC detector in their catalog, don't know if it would be helpfull.

Not sure why calls in the voice-mail wouldn't drop if calls on the sets do.

Do these calls happen at night too, and end up in the general mailbox? I had a cust with low milli-amps on line 9 once. This was causing phantom ringing. Are all calls answered by the AA? If so have you monitored the ports to see how many calls actually do disconnect in the AA? Are there any VM port contention issues?

Have you monitored with your test set while making a test call to verify/record disconnect failure for each c/o line?

Is their type of business prone to abandoned calls when the AA picks-up or too many rings occur?

Hi pabell,
You need the central office to provide a positive disconnect signal on the lines. The DMS-XXX can do that. Get a tester on the line and have him implement that as a test. You should see the vm port drop in about 1/2 sec. with disconnect. You may want to temporarily program the vm ports on your phone for the test. The disconnect timing does not change and was around 800 ms in our case on the line and default on the switch. (ACS 3.0)
Your carrier may charge to put the feature on (per line), but it will cure the problem. I had the identical problem at one site. This worked. We even talked Bell Canada into doing this at no charge since the tester could see that this was the fault.

Its all calls going into Voicemail ...main greeting ....personal mailboxes on all 4 Centrex lines
I think itpphoneguy is on the right track but I have never
had any issues with the centrex Trunks before like this..
I to have seen some strange things with Milli-amp issues
being to high (20-35 is good )getting echo sounds
buzzing and other related issues ....will see if can work with the Co tech to get them to try something while on site
to see if it makes a difference.

Let me know if that does it for ya. We have mostly DMS100's in my area. I might run into that someday.

Thanks
