[Android] Block Outgoing Calls

Can someone link me to an app that can block outgoing calls? I really need this as some people keep asking me to lend my phone for a call and I just can’t say no all the time! Thanks!

BlackList Pro

1. Blocking:
☆ Block call/text/MMS messages for a blacklist (a list of numbers)
☆ Block call/text/MMS messages for private numbers (no numbers, no caller id), numbers not in my contacts
☆ Block call/text message for pre-/post-fix numbers
☆ Exception list (don't block list) (PRO)
☆ Text filters by plain text or regular expression, prefix-matches, postfix matches.
2. Manage blacklist and logs:
☆ Options for an incoming call:
- Turn off ringer
- End call
- Optionally "pick up then hang up" (change in app's settings, may not work on 2.3+)
☆ Advanced number matching mode including exactly, start with, end with, contains, regular expression
☆ Widget option (can be set up from app's settings or widget (press HOME/menu/Blacklist/widget)
- Block numbers in blacklist excluded exception list (regular mode)
- Block all numbers excluded exception list (very useful when you are in vacation)
- Block all numbers (useful when you are sleeping)
- Turn blacklist off
- Auto SMS reply for blocked calls
☆ SMS blocked with/without logs
☆ Option to clear blocked missed call log
