Caller ID on analog sets through SX-200 Peripheral Bays on Mitel 3300

[Interconnectech]

Hello,

I recently migrated the bays from a Mitel SX-200 EL controller to a 3300 ICP MXe controller, re-using their Bay Control Cards, DNIC cards, and ONS/CLASS cards. Here's the issue I'm running into:

Inbound Caller ID (calls from the outside) is showing up just fine on the digital sets, and some of the newer analog stations that we installed. For some reason, their older analog sets do not display Caller ID correctly. When a call comes in from the outside, the digits to be displayed turns into a random string of 15-16 digits, and screws up the date and time. I know for a fact that Caller ID is enabled in the COS for all the analog sets. I went through the list with Mitel Tech Support, and it "should work" according to them. I even hooked up my test set to the circuit to see if I could hear the Caller ID tone being sent through the system in between the first and second ring, and sure enough, it was there. My initial instinct is that the issue is with the set itself, since it works on everything else and the COS is enabled to allow Caller ID. But I hooked up the phone to a POTS line with Caller ID, and it showed up on the set just fine. These sets worked before the cutover. Why aren't they working now? If anyone has any insight as to what is going on and how to potentially solve the issue, I'd sure appreciate it.

Thanks

What's the differences between the analog cards for the extensions that do work vs. the ones that don't work correctly? Are they the same part number, I suspect there may be firmware version differences/issues between the ONS cards themselves, try swapping the cards to see if the problem is the card itself. What software load is the system running, the first one we did with 9.x we had to upgrade twice for issues with the 4025's locking up in mid call due to messaging issues with the BCC III's, we had to go to MCD 4.0 to correct the issue and haven't had one since.

The ONS/CLASS cards are of the same make and model. We swapped cards, tried the ONS/CLASS cards in different bays (we have 6 SX-200 bays) and we ran into the same problem. The 3300 is running MCD 4.0 with the software patch, making the active software load 10.0.1.23. Since the cards are all the same and presenting the same issue with the analog sets, can it be concluded that the firmware is the same amongst all the cards?

Which raises another question, when you sync the bays up with the 3300 ICP controller, isn't the firmware changed/updated on all the cards?

Is there a way to check the firmware on each card?

The sets we have issues with are Cortelco Colleague 2211 sets, and I've received reports from other employees in the building that Caller ID isn't displaying right on some of the cordless Uniden sets either. I'm not quite sure of the model numbers for these sets.

I know that it isn't the sets because I tested the Caller ID out on a POTS line and it worked. Could it be an issue with the FSK generator in the Mitel?

The only card the ever upgrades (in per bays) is the BCC III, to review the firmware you'll have to remove the card and review the label on the back side with the rev level, the firm plid command doesn't work on 200 bays with the exception of the BCC, 2K per nodes list everything in the cabinet, to test the fsk theory, you'll have to swap the BCC III's. If that doesn't get it I'd look at the controller connectivity, all FIM, CIM, or a mix? You may need to move the connectivity around with just analog cards in the correct slots to see if it’s the connection to the controller, I doubt it’s the bay’s backplane if nothing’s changed but the controller type.

The BCC III's used to have FIM modules attached to them, but we did away with that and switched to CIM during the cutover. The reason for this was it's cheaper and easier to replace a patch cord than it is a fiber jumper, in addition to them being less touchy. I don't know if that would affect anything, but I thought I'd mention it.

We didn't change the BCC's themselves during the cut, and as far as I know, the 3300 doesn't change anything about the BCC's. It just downloads them so it can communicate back and forth. I don't think it's the connectivity to the controller, because this is the only goofy problem we've run into. Other than this, the phones perform normally. The working analog sets (Telematrix LP550's) show Caller ID information just fine on the exact same ports where we have the issue with the Cortelco's.

I'm with you on seriously doubting the backplane being an issue. The bays were never moved in order for anything to be damaged during the cut.

I have one more theory on why the Caller ID information isn't showing up correctly on these select few sets, though I wouldn't know where to begin to even start testing this theory:

The Telematrix sets are able to auto-detect the type of MWI signal and make whatever is thrown to it, whether it's an FSK tone or a voltage indication, work. Mitel Tech Support informed me that there are different ways to send MWI, FSK generators and voltage included.

On the SX-200, initially we had always set the analog MWI indication to detect the 90 volts as the proper method of indication.

The reason I bring up this MWI information is because it kind of correlates to what I'm thinking on the Caller ID. The only method that I know of to send Caller ID is FSK. Is it possible that the FSK the 3300 receives from the CO and the way it pushes it through to the sets is different?

If this is the case, maybe the Telematrix sets are able to auto-detect and interpret correctly whatever tone it receives to make it work, whereas this may not be the case with the older Cortelco's. Thoughts?
