We set up the incoming call rule with Prefix 0700 and Digits Length 4. When ePBX80 received a
called number with 0700, it will drop 4 digits after add **999.
 Now, if ePBX80 got an incoming call from ITSP with number 0700, ePBX80 will dial to
**999 (auto attendant). Then the caller can continue to dial the Extensions.
