The number of re-dial attempts is controlled by the WRONG_NUMBER_DIAL_RETRIES system
flag .
The default number of redial attempts is 3 . To modify the number of redial attempts, manually add the
flag to system.cfg and set its value to the number of redial attempts required.
The flag value range is 0-5 . A flag value of 0 means that no redials are attempted.
For more information about system flags see .
