Haven't tried it (yet) but if you dial your cell phone number, there's a very good likelihood you'll be put directly into VM. In other words, your cell phone provider picks it up as *the* number. I made the mistake of doing this to a friend of mine, using his home phone number, thinking his wife was at home and it would ensure him picking up. Unfortunately, his wife was with him and he thought he was being robbed!

I'll test it, just for phun, but if I were a betting man, I would say it'll ring back whatever number was spoofed.

I recently spoofed my number to my friend's cell phone number and dialed his number (to freak him out). Turns out, I got access to his voicemail and was able to listen to messages

Seems the spoofing is rather dangerous.

Anyways.. earlier I spoofed my MJ number to 000-000-0000 and and dialed my home number. After doing a *69, the operator said "This is your callback service. The last number receive was zero zero zero, zero zero zero, zero zero zero zero," so it seems that using *69 doesn't reveal the spoofed number.

This test was done on a Verizon land line, if anyone wants to spend 50 cents to test on other carriers it'd be appreciated, but as far as I can see, the *69 is fooled as well

I spoof my own cell phone number all the time.

When I call my own cell phone number, I don't get automatic access to my voice mail, the phone rings and caller ID shows my number.

I think it depends on how the carrier has set up voicemail. I can't access my voicemail without a password, even when I am calling form my own cell phone.

couch-potato... Just for the heck-of-it, have you tried using Stewart's method of putting an * after the first number? (See quote below.) I have used this successfully to not only get through to 800#'s being blocked but also fool the 800# ANI.

Stewart wrote:It appears that inserting a * after the first digit of a number changes the selected carrier, providing a workaround for various troubles.

Examples:

4*167895161 -- call Canada reliably.
8*004377950 -- sends your MJ number as ANI, instead of Choice One's (also spoofable). Useful when calling companies that use ANI to identify you or your location.
2*128675309 -- workaround for present spoofing woes.
5*122345789 (where 512-234-5789 is your own MJ number) -- test if your MJ is reachable from the PSTN (should show incoming on softphone and go to VM after 4 rings.

Sorry, I don't know whether you can dial this way from a phone connected to a MJ (they're painting my flat and the MJ is in a closet behind the plastic sheeting). Someone please try this for me. If it doesn't work, see if it works dialing from the softphone. I'll then edit this post accordingly.

Edit: It turns out that when dialing via MJ, you can't call with the above formats, because the software thinks that the number is complete after 10 characters and the last digit never gets sent. However, if you precede the number by *67 (normally would block caller ID but that's not implemented yet), then the call will go as expected. For example, dial *678*004377950. (If you are using an ATA or IP phone and have the dial plan set correctly, the *67 is not needed.)

Yes, I have tried all those - That's why I use my MagicJack to call my cell phone - because I have been testing all the different methods of calling to see what shows up on the caller ID.

What I meant is that when I spoof my cell phone number, and call my cell phone - my spoofed number shows up on my called ID, so I'm just saying that the spoofer works, but it doesn't take me directly into voicemail. as opposed to what happened to moocowh, I think it depends on your cell phone carrier. On some carriers it might take you directly to voicemail, but on my carrier, the phone rings, it just looks like I am calling myself.
