[cisco-voip] PRI 's Roll

[Fuermann, Jason]

I would guess that the all circuits are busy message was being played when their switch was completely down, and the fast busy was being played when the circuit came up, but their switch was not routing calls (still booting?). I don't know enough about their equipment to say for sure though. On a side note we know our ATT "special circuit" techs pretty well, so when we get an answer that doesn't sound right we just pass it by them to follow up on.

Yes, I agree I believe that all PRI's were with out power too. = No Roll
The AT&T Engineer was sketchy on the details.

Okay, but let me get this straight.

The in-bound caller gets the following:

(Busy out) = (actually put into out of service)

(All circuits are busy) =? Is what

In this case the in bound callers got a (fast busy) at one point and a (All
circuits are busy) another time.

Further, at one point we could see a PRI come back online from Cisco's RTMT.

In any event, thanks GUYS for the impromptu lesson.

ATT is bottom up for us. If your sales person is not lying to you I would
assume that the power outage affected all the PRI's and that's why the calls
didn't roll/hunt. More importantly you need to try and get this error
message yourself while monitoring the trunks (maybe you can narrow it down
to a channel). Additionally, we found if you "busy out" (actually put into
out of service) channels as Jason suggested, when ATT tries to send a call
to you they will provide a busy tone to the caller and not try another
channel.

Jason
I believe we are bottom up...
I am going to do some more research and query my sales person.
I will get back to you on this topic.
This is a great start...

Thanks so much, Tom

Ask these questions:

1) What order are they rolling in?
2) What distribution algorithm are they using?  (top down, circular, etc)

You can test each channel if you would like by shutting #2 & #3 down and
busying out all channels but one on #1.  Place test call.  Rinse and repeat
till you have tested all channels.

I typically request top down from the provider and do just the opposite
outbound.  If they are going top down 1,2,3 I will go outbound bottom up
3,2,1.

Guys:

This is my configuration
CUCM 4.2(3)sr4a (2) Cm in cluster
Cisco Unity 4.0(5.0)
Cisco 2851 Routers


Here is the situation: My client complains that external callers sometime
get an error message from our Telco Provider AT&T saying (all circuits are
busy).

I opened a ticket with the provider and they confirmed that there was a
power outage at one of their locations. Therefore, the Telco Provider AT&T
circuit has no power and our PRI goes down.

My client has 3 PRI's configured and they are supposed to roll from one PRI
to the next as call volume increases. The thing of it is my client has 3
PRI's with 23 channels each that are way-way under utilize. My question is
should the incoming calls just transition to the next PRI in the group? Am I
missing something? Is my Telco sales person says we are configured to roll
to the PRI. Why is it not rolling?
