ISDN2 DID (Direct dial)

  • For the business requiring 4 plus phone lines
  • With digital lines and caller reaching to your direct indail
  • One prime number can be assigned as main
  • Other numbers within the number range as an extension or group of extension
  • Each staff member can be allocated a direct line/extension number (if required).
  • Any one of the 100 numbers, or individual extension numbers, can be shown on outgoing calls.
  • When any member of a particular department (e.g. "sales") dials out, a specific "sales" number can be shown on those outgoing calls.
  • Specific incoming number/s can be designated for advertising/marketing and so on, allowing you to track how many calls are received on those numbers so you know which marketing campaigns are working for you.
  • The system is able to point 1300/1800 numbers to a designated indial number, which will display a name (i.e. "Yellow Pages"). This can help eliminate misuse.
  • Your Indial range is able to be relocated to different exchanges (conditions apply), giving your business the ability to retain its existing phone numbers and lessen the costs of re-advertising new business numbers.
  • Old phone numbers can be diverted for 12 to 18 months for $20 per month (no diversion charges apply) and sent to an indial number with a recorded message advising of the new number, then the call can be transferred to reception or other extensions
