Benefits of SIP Trunking vs. ISDN PRI

• Reduce Usage Costs –Save more on monthly telecom costs. SIP will allow for consolidation of DID numbers into a single location eliminating the need to for expensive trunking and phone equipment at satellite or home offices.

• Aggregation - Centralize administration of local numbers and trunks at each satellite location.

• Reduction - Elimination of multiple lines at each satellite location.

• Scalable - Purchase the exact number of call paths needed and easily expand or contract capacity as required by your business. ISDN PRI scales in increments of 23 call paths vs. increments of 1 in the SIP world. SIP also allows you to add DIDs in increments of one vs. PRI which requires a block of 20.

• Flexible– SIP allows for shared communication across a single IP connection. This allows voice and data communications to be consolidated to a single network link vs. PRI which does not allow for Internet/data communications.
