I've got a client with an IPO 500 that is having problems with incoming calls when caller ID is enabled. The inbound calls are set to ring the receptionist, overflow to two other people, and then hit VM. When CID is enabled the receptionist can pick up the phone and it stops ringing but the caller isn't there. When they hang up the phone it starts ringing again. Depending on how long it takes them it generally overflows to the two other people and they can generally retrieve the ringing call.

Version is 4.2.14, lines coming in on analog, all digital stations.

Was this system on a previous version? Did they just go up to 4.2.14?

I have had a few systems do some weird crap on that new release. I would take them down to 4.2.11 and see what happens.

They have had a variety of versions as I tried to find the problem. I'll have to check and see what the previous one was.

The only problem I have had with Caller ID w/ analog lines on an IPO 500 (all versions...currently 4.2.14) is the amount of time it takes for the ID to appear on the phone. When a customer calls in to the location, by the time the Caller ID displays on the receptionist phone, the customer has heard approx 4 rings, wheras it has only rang twice on the reception phone. I wish they could find a way that by the 2nd ring the customer hears, it would be the 2nd ring on the phone system as well.....

CID comes between the 1st and 2nd ring. IPO waits until it either captures the CID, or received a 2nd ring without CID before presenting the call to its destination (be it an extension or hunt group). Without this operation, the phone would ring, and then the CID info would appear.

You might want to test with a butt set to see what the caller hears, and how many rings come in at the MPOE, and when the IPO starts ringing.

I have simulated with a butt set, and it is as the customer reports. They hear anywhere from 3-4 rings before IPO is ringing. I understand that the IPO is waiting for the CID, but on Nortel CICS/MICS (for example) the lines ring right away and will present CID on the 2nd ring. Just wish IPO could behave the same way.

I would also clamp a butt set on the trunk and make a call in on it. Monitor and see what happens. You should hear the tones when CID is transferred, then what????

Does this happen on all ATM4 ports?

You can eliminate 2 ring delay by going to trunk type and changing it to Loop start. No caller id will be delivered though.

That's how I have it set now. Just loop start. They do not use CID now, but may in the future. It does happen on all ATM4 ports.

Just for an update, we went through Catalyst support and are at Avaya Tier 3 support. It's programmed correctly but not acting correctly.
