I know that holding the "1" on the keypad will dial your voicemail account, but I do not know what phone number that it should be dialing when I do so. I also know that I can dial my wireless number from any other phone to access the VM, but I would like to do so from the phone itself. Thank-You!
When you press and hold the "1" key down, it is a speed dial and will generally display the number it is calling (not on all phones).
I had a problem with the programmed speed dial number on my new BB... I called Rogers tech support and they gave my the local VM access number. in the "Options" setup, I went to the "Speed Dial" list to correct the problem.
So my suggestion is that you look in your speed dial list, which is likely in the "options" or "setup" menu, depending on what phone you have.
