Traveling abroad but afraid of expensive call charges from your cellphone operator? Why not just dial the number from your cellphone's address book using a landline phone abroad? Introducing.... 

Traveler's DTMF Tone Dialer v1.3

Simply put your phone's speaker to the mouthpiece of the public phones, hotel phones or other landline phones and the Dialer will dial the number from your address book. Even more, it's intelligent enough to strip off the international country code and combine it with the dialing code that your hotel or public phones need. 

With the Dialer, you can:

• Select phone numbers from your address book or enter your own number.
  
• Recognize several phone number formats from your address book and make variations of the phone number. The variations are a combination of the phone number
  - with country code, for international phone numbers
  - and without country code
  with user-supplied dialing codes ("prefixes"). With this feature, calling a number abroad are just a matter of clicks. You can supply as many prefixes as you want and the Dialer will faithfully present those combinations for you to choose to dial.
  
• Use the Jog Dial for convenient navigating and dialing. Don't get messy with having to hold and tap the buttons on the cellphone and at the same time hold the public phone's mouthpiece. Conveniently use the jog dial to navigate and dial.

Bonus features:

• Hotkey facility: Assign a hotkey for the Dialer and you can then start this app with a single touch either on flip-closed or flip-opened mode.
• Flip-closed mode: Get the most essential dialling functionalities even when your phone's flip is closed for your convenience only.(Sony Ericsson Px phones)
• Keypad dialer: dialer with big keypads -- you can dial with your thumbs!
• International Country Calling Codes: look up and copy international country calling codes.

Example:

Your friend, Irene, is living in USA and her phone number is entered as +1 234-567890 in your cellphone's address book. You are going to visit USA and give her a call from a hotel in New York. The hotel supplies a dialing code for outside calls, i.e., you have to prefix her number with "09", but without the USA country code "+1". After entering "09" on the Dialer's prefixes settings, the Dialer will present you 09 1 234 567890, but also, intelligently, 09 234 567890. You just have to use the Jog Dial to select and dial 09 234 567890 and put the cellphone to the hotel's mouthpiece. It's that simple.

The Dialer is able to recognize several ways people enter their phone numbers and recognize the country codes from them. If it, somehow, doesn't, you can always supply the length of the country code.
