DISA: Direct Inward System
Access
DISA is a relatively
new feature of Business Telephone Systems (PBX systems)
You must have heard many a
times when you call a Business or an oraganisation, an automated message
asking you to dial a digit to access a particular person &/or a
department,
Press 1 for Sales
department, press 2 for customer service, press 3 for support, or else
wait for your call to be attended by the next available operator.
This is it - this feature in
the PBX System is called DISA
Most of the digital & VoIP
PBX Systems have built-in DISA.
A few analog PBX Systems &
the earlier generation systems need an optional Card to go DISA.
Usually
DISA also works as a TEL/FAX Autoswitch, to automatically
distinguish the Fax or Phone call & send the incoming call to the desired
extension. The fax is received automatically silently or maybe with a
couple of ring tones in the fax machine (configurable).
