If you routinely call into voicemail boxes, punch in department extensions or dial other number combinations that require you to pause and wait before entering additional input, reader Meseta shares a simple tip. Insert commas into your contact entry to force pauses.
On Android, adding a comma in a phone number inserts a two-second pause while dialling. This allows you to dial a phone number and then an extension or automatically select menu options.
For example I use the Skype To Go service to call abroad, a process which involves dialling a number (e.g. "02030193509"), waiting for it to ring and connect, bringing up the dial pad, pressing 1 to access my saved contacts within the Skype To Go system, and then pressing 1 again to dial my first contact. Instead, the same thing could have been achieved simply by saving "02030193509,11" in my contacts.
Similarly, if you frequently need to dial a phone number (e.g. "1233098149") with an extension (e.g. "1135"), you could save "1233098149,,1135" in the contacts.
This trick also works on the iPhone; other phone users will have to chime in with the trick that works on their phones. Have phone tip, trick or hack to share? Let's hear about it in the comments.
