Prefixer

Prefixer - the original utility app that will prefix, suffix and/or replace numbers in your calls on-the-fly, based on your own set up rules. You no longer need to manipulate or change your contact list just because your calling plans or habits change!

Great for country codes, calling cards, Google Voice, PBX, Centrex solutions, the problematic Facebook contact sync and similar!

Prefixer also contains an highly customizable Call confirmation functionality, an on/off widget for your home screen, selectable expression templates and a regular expression cheat sheet!
You can add and share setup rules with your friends using QR codes or URLs.

The rules in Prefixer are set up using a number of conditions and actions that are easy to configure, enable and disable. When the condition(s) in a rule apply – the action(s) are executed.

Supported conditions:
> Number pattern using regular expression
> Contact list existence
> Member in group (Android 2.0+)
> Roaming
> Day of week
> Time of day

Supported actions:
> Remove characters
> Add prefix
> Add suffix
> Add original/manipulated number to call log
> Lookup contact (caller id)
> Call confirmation (standard, manual and party mode)
