Call Waiting Enabler
Call Waiting Enabler is a free software for Android phones for enabling call waiting (GSM feature to receive new calls while in call) when it is not possible via built-in Settings interface due to GSM operator incompatibility with phone software (most likely this condition is met when mobile network doesn't properly respond to outbound caller id status request).

Internals
Call Waiting Enabler requires the following permissions:
- android.permission.CALL_PHONE
- android.permission.CALL_PRIVILEGED
- android.permission.MODIFY_PHONE_STATE
All these permissions are required to dial MMI codes. This software dials *43# to activate call waiting, #43# to deactivate it and *#43# to query status. This app was created mainly because there was no such app in Market and finding these codes wasn't very straight forward (when searching for alternative solution to enable call waiting on Android phone). A good MMI code reference can be found at: http://code.google.com/p/android-roms/wiki/Secret_Star_Codes
