Benefits of Using a Demarcation Device When Integrating Legacy Voice, SIP Trunks and Microsoft OCS R2

The term “trunking” has been used in the telecom industry for a very long time. The term “SIP Trunking” is a VoIP-related term with Session Initiation Protocol (SIP) being used for initiating and tearing down calls. The SIP Trunking market has seen growing interest over the past two years and has now come into the mainstream with offerings from the major service providers. Organizations are now migrating from traditional Primary Rate Integrated Services Digital Network (PRI) based PSTN connectivity to IP-based converged networks using SIP at an increasing rate in order to achieve telecom cost savings.

Many organizations are already benefiting from VoIP by transporting calls over their IP networks. By implementing SIP trunks, enterprises can further reduce costs associated with PSTN access. Because SIP trunks are used for local and long distance calling, traditional TDM links can be significantly reduced and their use can be kept limited to providing PSTN backup and emergency 911 services only.

The far reaching benefit of deploying SIP trunks in the enterprise is the ease of implementing Unified Communications (UC). SIP trunks allow organizations to consolidate telephony into datacenters and allow branch offices to be linked with datacenters for providing same UC capabilities across the entire organization.
