Utilizing SIP

Flexible and Cost Effective

The Session Initiation Protocol, or (SIP), is a reliable, flexible and cost effective transport technology used to reduce disaster recovery times and eliminate traditional and costly trunks and circuits.

As a signaling protocol, SIP is transported over an IP network and used to connect enterprise PBX systems (including Cisco Unified Communications Manager) to the Public Switched Telephone Network in place of traditional TDM facilities such as PRI voice circuits.

Utilizing SIP over MPLS and Ethernet removes the limitation of 23 to 24 voice paths per circuit, greatly increasing flexibility over how the network is designed and utilized.

Unlike time consuming TDM voice circuits, SIP customers can automatically deliver inbound DID traffic directly to a second data center for real, seamless disaster recovery. No more down time and manual intevention.

In the future, support for Instant Messaging, Presence, and Video calls via SIP will be provided and are part of the current industry Request for Comment or RFC.

Early Adoption with Universal

Universal was early to recognize and apply the significant value SIP would have on our clients and their voice networks.

Over the past five years, we have worked closely with vendors like Avaya, IPC, Nortel and Verizon to develop meaningful proof of concept exercises while ensuring our client SIP certification plans are completed and optimized.

Real Dollars Saved Using SIP Trunking

The right environment for SIP Trunking includes anyone using PRI circuits across two or more locations. By replacing multiple PRI circuits with an Ethernet (10Mbps) SIP Trunk, typical clients realize over a 30% savings in overall recurring trunk costs.

By utilizing SIP with a quality PSTN provider, the network is a seamless, fully active disaster recovery service for voice environments.

Beat the Budget Crunch

Clients looking for fast savings, should quickly move to understand, test and evaluate SIP technologies. With Universal, you can begin offering this technology to your organization as cost-effective method for delivering voice services, as well as a critical disaster recovery tool for voice services
