Get tired of having to hide and display the pesky number pad on your iPhone in the middle of a call? I have a tip for you!  All you need to do is add commas to your contact number.  In the telephony world, commas are the equivalent of pauses. Therefore you can add commas followed by more numbers to dial the extension.

Example:  417-555-5555,,,,304  This will call the number pause for 4 seconds then dial 304.

This is ideal for business offices and technical support lines.  Now that you know the secret, get to work on your contact list and let us know how it works for you.
