Digitize your traditional analog lines for greater efficiency

ISDN PRI supports up to 23 voice channels and one D channel, allowing for faster connections and clearer signals than analog could ever deliver.

And with greater efficiency comes savings! As one digital card replaces as many as 24 analog cards, you’ll save on hardware-related costs, and choosing one ISDN PRI line over individual dedicated circuits will save you even more.



  • Major operational, maintenance and hardware-related cost savings
  • Network reliability ensured by dedicated non-fluctuating speeds
  • Greater control over your connection as all calls are easily managed with configuration flexibility
  • Clients will never get a busy signal thanks to our backup D channels and overflow, which automatically re-routes calls to another PBX-served number
  • Unlimited 10-digit extensions for various divisions or employees
  • Release Line Trunking to release lines associated with a recently transferred call, thereby freeing resources on the PBX
  • Direct Inward Dialing (DID) to enable an outside caller to call an internal extension without passing through an operator
  • Call-by-Call Routing to allow users to control the min(s) and max(s) of calls for trunk groups directly from the PBX, and manage routing of incoming calls based on the telephone number dialed
  • Vanity Numbers to create personalized and reserved DID numbers
  • Line Hunting to route incoming calls to the next available line
  • Also available: Call Display, Call Forwarding and Three-way Calling
