ISDN PRI Service

An ISDN PRI circuit is an all-digital business service that interconnects your on-pemise PBX to the Public Switched Telephone Network (PSTN).  This solution is often more cost-effective than having numerous individual business lines. Just one ISDN PRI circuit provides your business with up to 23 individual 2-way channels for voice communication, and reliable communications that can be scaled on a per channel basis.  The experts at CISP will find the best solution for your business based on your needs.

ISDN PRI service is used by businesses to provide local and long distance voice service as well as other applications including video conferencing, fax, and dial-up.  An ISDN PRI provides increased efficiency through a PBX phone system by setting up and breaking down the PRI phone calls faster than a regular voice T1 or phone lines. An ISDN PRI offers robust features like:

  • Local & Long Distance Voice Service
  • High Speed Fax Transmission
