Moved phone line to M1 and lost caller ID

[AnotherOne]

I just changed my phone line for the security system and now caller ID no longer works on that line. I have verizon phone service and there are 2 wires running to my Elk M1 for the phone system. The M1 can disconnect the lines and call out fine, and everything else seems to work - answering machines, ringing, etc. just no caller-ids.

Any ideas?

Thanks.

If you have a lot of phones and answering machines and such then you might just have too much of a voltage drop. Maybe try to unplug everything but the elk and one phone and see if it works then. If so, try plugging in a few more things and keep trying until it stops working again.

Okay, so I went into the RX31 jack and shorted the r1 and ring together and the t1 and tip together and now the caller ID works just fine.

So it would appear the the M1 is doing something that is causing the caller id signal to get too low or something. I'll measure resistance and see what I find.

Somethings not right, if you shorted R1 to T1 on the RJ31x something should smoke when the phone rings.

When did he say that? In any case I don't think anything would be harmed, I imagine the phone company makes allowance for that.

My mistake, I see what was done now. No clue on the telco's short protection but i know you'll fell it if you are holding them.

The M1 looks like it's having a problem.

If I disconnect the R1 and T1 wires from the M1 (so it doesn't think the phone line is faulty) and messure impediance on the M1, I get .1 ohms between the T1 and TIP (which is good) and I get 2 Megaohms between the Ring and R1 (which is very bad).

I'll have to call the elk support folks next week to see how I should diagnose this.

Turn power off to the M1 and measure the resistance through the M1. If the M1 detects no phone power, it will switch from a telephone connection to powering the inside phone lines itself.


Look on the keypad under the Menu 8 where the last telephone voltage is displayed. See if the voltage on the telephone line is low. 30 volts or less.

Caller ID should work.

Okay, telephone voltage is 55 volts + or - 20%

Turned the M1 off and pulled the eurostyle plug and measured directly on the M1 board with nothing plugged into the 4 phone connectors and the resistance is the same as before -

tip to t1 = .1 ohms
ring to r1 = 1.99 Mega ohms

I just called Elk support and they said caller ID may not work through the M1 and that this is a known problem and they do not have a solution.

WOW! That's not good. I use caller ID extensively for filtering out junk incoming calls or invalid CID information calls. I haven't hooked up the elk to the home phone yet except for a small trial...This is definitely not good. Let's hope there is a solution or at least a good explanation soon.

In a pinch you can use Nextalarm with their ABN to report over the internet. I have been using them for a year with no problems. Others seem to be pretty satisfied.

There are many alarm panels out there with similar problems and ELK is definitely not alone with this.

Caller ID works with my ELK M1G, no problems at all.

Phone service is via the cable company with a Motorola 5120 Surfboard cable modem.

In a pinch you can use Nextalarm . . .

Also -- a bit involved, but still -- in a pinch, take your line onto another pair (parallel to the house line) and split it out at the jack(s) into stand-alone caller ID displays. House phones on the RJ31X, displays on the direct line. This way ELK still has line priority in an alarm.

Not practical? Depends on your needs... :-/

My Caller ID has always worked fine, coming from a Vonage router to the M1 to a NetCallerID unit and some phones.
