TAPI dialer Disconnect Unknown when a lot of people dialing

I created a TAPI client application which seemed to be working OK until the users increased from 28 to 35.

Occasionally when a call was placed the trace log output would state it was placed successfully but then it would disconnect within 100ms with a callstate of "disconnect unknown". Since the users have increased from 28 to 35 this happens a lot more.

(There are no messages in between these 2 specific to the placed call - sometimes an IDLE message comes through from the last call but not always.)

We have an Avaya IP 403 PBX.

Any ideas, your help would be really appreciated?

THis s way out in left field, but have you checked that your 'SMall Community Networking' license is valid?  I may be wrong, but I think you have to either have and SCN License or at least one PMP license for TAPI to work.  I can't explain why it worked before, might be related to the fact that you have a 403.  If you wanna send me the app I can test it ona  406v2 and/or an IP500 in our lab.

Turns out we were running out of lines because the phone system had been misconfigured for some time.
