  • Each data channel provides signaling for call set up functions
Problem Solution
Multiple dedicated fax or analog lines are costly ISDN PRI/T1 services give the end user the ability to consolidate all fax and analog lines on the same circuit without paying any monthly recurring charges for dedicated fax lines
Limited feature compatibility with current service and phone system Many phone systems can provide enhanced features such as unified messaging but are not compatible with standard phone lines. ISDN PRI provides a strong integration to extend those features to the end user
Lines dedicated for multiple communications uses such as inbound hunt groups, outbound calling, dedicated long distance and toll-free services are inefficient and costly Dynamic channel allocation allows end users the ability to scale back the total number of lines and still provide the same functionality saving money over dedicated lines
