If you are using the Outcalling feature, the subscriber might include the account code FAC and account code in the dial string for message notification. In this case, the FAC, account code, and notification number are all part of the destination number. When the system constructs the dialing sequence, the account code appears twice, once as the account code and once as part of the destination number. To avoid this duplication of account codes, it is recommended that subscribers be instructed not to include the account code as part of the dial string for message notification.
However, if subscribers are including authorization codes in the dial string for message notification, there is no conflict with account codes. Subscribers can continue to include the authorization codes.
