amorusocc, seems you're feeding the walljack that comcast modem used to feed to (using Ooma) so alarm line seizure is working and you do see calls made to alarm central on Ooma call logs when doing phone testing?
If that's the case, try programming your panel to use *70 prefix (disable call waiting); I found this to work best for my alarm.
You can also try dialing prefix *98, *99 Here are the complete star codes: /viewtopic.php?t=14903
I talk about my alarm dialing prefix here: /viewtopic.php?t=8957#p62487

Here is a snapshot from my screen.

In addition to what others have recommended; some alarm panels monitor polarity and standing voltage of the line it is connected to. Try reversing the wires, i.e. polarity at the jack the Telo feeds.
Nothing we can do about the Telo output voltages. I never did get a chance to compare my ATT land line voltages to the Telo output voltages; if anyone could comment it would be interesting to see:
1) On hook
3) Off hook
Normally a land line central office would provide
1) On hook 48VDC
2) Ringer 96VAC@20Hz
3) Off hook 7-10VDC
Switch polarity at the jack, clear the fault message of the panel and then see what happens. Let us know please.

Keep this in mind- the green (TIP) wire is tied to earth ground (somewhere), so the Linx, and the Telo my cause a ground loop through their power supplies (an AC loop), which can cause lots of noise. The only solution is a coupling transformer (some older panels have it on the PCB, but yours is likely newer) or a differential amplifier (such as an op-amp) which has an isolated supply (or a great power supply rejection rato- PSRR), and very good common-mode rejection ratio (CMRR).
It sounds like your alarm's problem is not noise, however, since ADC is able to communicate with it. But you could connect a battery-powered audio amp with speaker (used to be called a signal tracer) to the phone leads to listen to the signals. I've had to do that in the past with alarm panels connected to a cable modem/telephone interface (SLIC). Murphy and billinin sound like they know their alarm and telco stuff. I am thinking that ADT will need to provide you more tech help with their panel.
You've probably looked at this thread: viewtopic.php?f=9&t=11514
You probably have the Linx device set to Alarm mode in the MyOoma preferences. That really should work for just about any situation with nothing else needed.
If the kiss-off is not received your panel should call again two or three times (at least, and this can be changed in most panels). This is another situation in which the signal tracer is handy- you can actually hear it. Another consideration is that you might ask ADT if they can tell you how to change the modulation scheme to something more compatible with your VOIP, the data exchange will be slower but more reliable. Others have said that ADT uses Contact ID format, and that can cause a problem. But it should be okay with Linx
Keep us posted!
The cable folks tried a few others and were able to get our phone to ring, but each time they changed the box (three times) different problems went away, and new ones occurred. It was a big time sink at a time when my consulting business was extremely busy.
It sounds like your alarm panel defaulted to looking for signals that meet US and international standards. Does that imply that this problem is the panel's fault? Maybe all phone service providers should just ensure that their equipment meets the standards, so people don't have to invest time looking for work-arounds.
