Inbound calls over PRI failing, Outbound OK

[VTTD1870]

Have customer who is having issue where Inbound calls over PRI are failing (intermittantly), however, Outbound calls are OK. I assume this is a carrier problem but is there something I can do to confirm this?

Make sure you're sending out the correct caller ID information. I had a similar issue with a T1 that was resolved by adding the full phone number to my individual ICRs.

Any errors in system status ?

What do you see in the Monitor? Do you see the incoming call?

Problem only seems to affect inboiund calls (intermittently). No errors in system status. When experiencing the problem with inbound calls, I don't see the calls in System Status. Haven't used Monitor.

Use Monitor as System status does not see calls the way Monitor sees them.
When you can dial outbound then inbound must be an issue like this:

Provider is not sending the calls to you.
There is no incoming call route.
There is no (correct) destination in the incoming call route.
The destination is not available.


BAZINGA!

I'm not insane, my mother had me tested!

when you use monitor just enable the ISDN filter options and leave the rest unchecked, that way you only see what is happening on the PRI and don't have the clutter that is not important for you at the moment.

Is this a full PRI or a partial?
If it is a partial, then sometimes all channels need to be enabled but the provider only uses / allows the amount of channels it is provisioned for.

Interrupt the silence only if you improve it by saying something, otherwise be quiet and everybody will be grateful.

What do you mean when you write "failing"? What happens? Busy, recording intercept (i.e. you're call cannot be completed...), ring no answer?

There are lots of possible reasons, but the usual cause is some sort of discrepancy between your settings and the carriers settings.

Check the easy ones first: protocols (yours versus the carrier's), number of incoming digits sent, ascending versus descending, number of channels you have turned up versus the carriers, and incoming call routes (got everything there?)

It's not rocket science - if it was, I wouldn't be doing it.
