Account Codes

Configure Account Codes

Account codes provide a tracking and security mechanism for specific call types by requiring a special code be dialed before certain outbound calls are allowed.  When account codes are enabled, a caller will hear a second dial tone, and will need to dial a valid account code in order for the call to proceed.

  1. Log in to the portal at https://commportal.calltower.com.
  2. Click on the Settings tab, then the Account Codes tab.

clipboard_e8b0745ad92c45be63597b96b2a8e4b02.png

  1. By default, no Account Codes are configured.  Choose the number of digits you want to use in your Account Codes and enter that value in the Account Code Length field.  
  2. If Validated Account Codes is selected, then the Account Code entered during a call must match a code on the Account Code list.  Otherwise, the call is rejected.  If  Validated Account Codes is not selected, any number with the correct amount of digits can be used for the Account Code on an outbound call.  Validate that this setting matches  what you want and click the Apply button. 
  3. If you’re using Validated Account Codes, click on the Edit List button to create your list of valid Account Codes.
  4. Enter each Account Code and brief description, then click the Add button.  To delete an Account Code, click on the X to the right of the code.  When complete, click the OK button.

  1. Configure the types of calls that will require an Account Code.  Check the appropriate boxes under Call types Requiring an Account Code and click the Apply button when finished.  If International is selected, an Account Code will be required for any call made outside the US or Canada.  This includes foreign countries that are reached by dialing an area code.  (For example, Bermuda telephone numbers are in the format 1-441-XXX-XXXX.)  CallTower does not use traditional definitions of Local or Regional calls.  We suggest for consistent operation of Account Codes, you either have Local, Regional, and National call types all selected or all unselected.  CallTower does not use Carrier Dialed calls.
