VoIP provider Skype lets you make PC to PC calls or make calls from your computer to a telephone. But if you live in the US, up until now when you made a call from Skype to a telephone, ther person you were calling wouldn't see your number on the caller ID. They's see some random string of numbers like 000123456.
Skype has now added a Caller ID option that will let you use your SkypeIn phone number or your cellphone number for Caller ID purposes. To activate the feature, just log into your account through the Skype web site, and select Caller ID from the Account menu. If you have a SkypeIn number to receive phone calls, that will automatically be selected as your new ID. If you'd rather use your mobile phone number, just enter the number and Skype will send you an SMS with an activation code. Note that it could take up to 24 hours before the changes take effect.
If you have multiple SkypeIn numbers with different area or country codes, you can also select an option that will automatically display a number that's local to the call destination when available.
Skype has offered a similar Caller ID feature for European customers for a while now.
