calls not going to coverage, fast busy

[AVAYAPro]

I have the following extension provisioned. On all incoming calls from external sources via the ISDN-PRI, the caller will hear silence for 3 seconds and a fast busy:

Extension: 1674 BCC: 0
Type: virtual Security Code: TN: 1
Coverage Path 1: 30 COR: 3
Name: MM TEST EXT Coverage Path 2: COS: 3
Map-to Station:

Time of Day Lock Table:
Personalized Ringing Pattern: 1




Survivable COR: internal
Survivable Trunk Dest? y

13:14:38 idle trunk-group 5 member 24 cid 0x20f

Anybody have any ideas on what I can look for that might explain this? All other stations of COR 3 are covering normally and calls from internal extensions go to coverage normally.

Thanks and regards...

Check you Public-unknown for extension range 16xx. Make sure you are sending that extension number over to MM.

That trunk is actually utilizing unk-pvt and the 1xxx extension range is in that table. On another note, other extensions in the 1600 range are covering normally

I had the same denial event on calls landing on MM, but only when they came in on some of my toll free numbers. Avaya ended up changing the send callers name to "n" on the TG form.
Not sure if that helps or not.

No joy, same result.

That denial event is related to Q.931 messages/timers according to the documentation here:

http://downloads.avaya.com/css/P8/documents/100059379

(See the cause value 102 section)

We are having an issue with certain phones failing to register correctly due to Q.931 messages not being received in a timely manner, we have isolated it to a particular model of Alcatel network switch, although we still haven't identified a fix yet.

May be completely unrelated to your issue but thought it was worth mentioning.
