Caller ID on loop-start CO trunks 2

[HossBoss]

I have CM6 running on a 8300/G430 with a MM711 8-port analog/trunk card.
Caller ID feature is active and verified on all 5 of the loop-start trunks but I only get caller info on 1 of the 5 COs. I get caller info on all 5 COs when I put an old caller ID box on each circuit but only get it on 1 CO when connected to the MM711 card.

Any thoughts on how else to troubleshoot this? Would tip/ring being flopped have any impact on caller ID?

I've moved ports, gateway slots and tried a new MM711 but the test results are the same….I always get ID on the one circuit, never the other 4.

Thought?

Thanks for the feedback!

the 1 line that you do get caller id, have you tried moving that line to another port on the mm711 board,and see if you still get the caller id?

 

[HossBoss]

I did. Every time I move the 1 "good" CO to another port, slot or MM711 I was able to get ID.

so the board is good then, I would work this through the line provider and yes I know it works with the caller id box but still the co maybe needs to make a tweak on the circuit

Strange... are they all the same trunk group?

 

[HossBoss]

Correct....all the same trunk group. I changed the "Receive Analog Incoming Call ID" on the trunk group to Bellcore, NTT and V23-Bell to make sure it wasn't a matter of the 1 of the 5 COs being configured differently or using different CO equipment...but no change.

disconnect the trunk and put a callerID analog phone right on the trunk and see if you get callerID when you call it. If you get it there, the pbx will pass it if it's using the correct hardware and software for callerID support.

have you tried calling the numbers directly when connected through the trunk group and receive caller id?

 

[HossBoss]

I haven't tried a physical phone, just the caller ID box from the 90's. On the 1 good CO, I get caller ID on both the box and the phone on the PBX when my test call rings through CM processing. On the other 4, I get caller ID on the box but not when running it through the CO.

Could the T/R being flopped cause this? Perhaps out of range voltages?

 

[smokinjoe2938]

try this, create several trunk groups all programmed the same way, put 1 trunk in each trunk group,make the incoming destination the same as the main group, call the trunk members and see if you receive caller id.

Final fix was to newer hardware vintage. Both current cards firmware went to 79....the latest given the hardware vintage. Still doesn't make much sense since we had good caller id on one of the 5 COs.....even when we moved the circuit to the other MM card. So, hardware never appeared to be an issue.

Thanks for all the suggestions.

thanks for the answer so have some pink!
