Hi everyone, I love this site. I have my MJ connected to my cordless phone base which has four hand held units. My outbound CID works fine and my inbound CID shows the number of the phone from where the call is coming from. It does not show the name. Instead of the name it shows their number. So when someone calls me I see their number twice. The top row in my CID display should show the name but it only shows their number. My computer is connected directly to my router using a CAT 5 cable. And MJ is connect to one of my USB ports in the back of my PC. The USB port is 2.0 I am using the small cable extender on my MJ. Do you guys think that that if I add the resistor to a phone extention, like the one picture on this thread, will solve my CID issue? Any feed back will be greatly appreciated.

Thanks,
Magnum68

No. MJ does not currently support CID Name.

Any word if MJ will support CID name sometime soon?

When I do the resistor fix I can make calls but I can't receive calls.
When I call my MJ from my cell, the soft phone pops up and then it disconnects??

Thanks to Snafu and LikeMagic for your posts and insights regarding the 100k resistor. I got my whole house up and going with caller id like a charm.

I found out my problem with the caller id was my cordless phone. I tried a different phone and it works fine.
i was thinking about trying your fix but wanted to try a new phone first. I really dont like the phone I was using anyway.

Well I've tried everyway I can on the resistor fix and I end up with the same result.
I can make calls, but I can't recieve any calls. When the MJ number is called it disconnects after 1 ring.
I've read and re-read the fix but, I have to be missing something.
I'm trying to do a whole house fix..I've put it in the coupler, I've cut 4 inches off a phone line and used a 1 into 2 jack, and I've put it in the box outside.
I'm going across the green and red wires right????
Any help please!!!!!!!

Does it disconnect with nothing plugged into the mj phone jack? If it does, I would suspect a bad mj. If it does not disconnect, I would try adding one phone at a time and testing with each addition. If you have added the 100,000 ohm resistor, I would verify that it is the correct value. Too low a resistance could also cause your problem. Good luck.

Hey snafu2. I know that you say to use a 100k resistor & this might be a really dumb question...but, does the tolerance rating on the resistor matter?...Thanx in advance! Very Happy

snafu2 · MagicJack User Joined: 28 Nov 2007 Posts: 35

No. The value is not critical. I would guess anywhere between 90k and 120k would be alright.

That's what I thought...Cool...Thanks for the info...You are truly "Da Man" for figuring this out Very Happy

I dont really get why we need the resistor though... can anyone explain?
Thanks

OK kumar, this my take on the CID issue.

Ideally, from a DC standpoint, one would want a telephone device to look like an open circuit to the line. This would allow an infinite number of devices in parallel without swamping the line to the point of drawing dial tone...off hook condition. One would normally want to avoid low resistance across any device connected to the phone line.

In the real world you can get by with a little resistance if it is well above the point of drawing dial tone. CID information in the form of data pulses can be distorted by capacitance of some phone devices and by long phone lines. If the CID circuitry is not designed to handle this, errors occur preventing proper CID display. The resistor dampens the voltage overshoots caused by the capacity, thus making it easer for CID decoding.

Hopefully, MJ has corrected this in the units the are now shipping.

I am probably totally wrong about all of the above, but this is IMHO what's going on.

Another satisfied user of the 100k-Ohm resister fix!!!!

Some additional help for those wanting to try this fix...

I used a 100k-Ohm Resistor (1/4 watt 5% tolerance) from Radio Shack. The catalog number is 271-1347. You get a package of 5 for 99 cents.

Instead of sodering, I used a surface-mount telephone jack that has two places to plug in a phone. I connected each of the 2 red wires and one lead from the resistor under one screw and the 2 green wires and the other end of the reisistor under another screw. Then I run a phone cord from my magicJack to one port on this phone jack and then run another cord from the other port on this jack to my phone.
