Enterprises are adopting solutions that enable convergence to a more cost-effective packet network for integrated voice-data access and delivery of enhanced services; seamless connectivity between different types of enterprise CPE (both TDM and IP-based); carrier-grade reliability & voice quality in a converged, distributed environment. However, as enterprises and business grow either via acquisition or organically, issues with ensuring the communication infrastructure remains flexible dominate. Security, interoperability between multivendor VoIP equipment, SIP interface issues between enterprise and network, protocol (SIP, H.323) interworking, and uniform accessibility of features for all of the enterprises users are seen as primary challenges.
The enterprise challenges present a unique opportunity for the carriers to play a significant role in its evolution. Service providers who SIP-enable this network access will be poised to not only capture both voice and data spends, but also to offer new multimedia based real-time services to increase ARPU and decrease churn. However, the growing trends in use of IP networking and IP-PBXs for voice communications by enterprises also place an increasing burden on the service provider to offer a flexible, secure and converged access to the enterprise.
Enterprises who make avail of SIP Trunk services derive greater network and administrative efficiencies. A SIP Trunk is essentially an overlay over the IP network enabling rich-media service delivery over the converged pipe. Offering support for business trunking via SIP allows for carriers to retain their voice subscribers as they transition from remaining converged islands to extending convergence beyond their network boundaries.
The Verscom Enterprise SIP Trunking Solution
SIP Trunking is the next step in the evolution of the converged access. Network operators who SIP-enable the subscriber’s broadband access transform themselves from mere bandwidth operators to service providers enabling advanced multi-media SIP services. The modular and innovative solution from Verscom equips providers to both build an end-to-end SIP trunking solution as well as manage the services delivered on it. Verscom’s multi-level security architecture, its flexibility in treating signaling and media, and its field-proven record ensure service providers can immediately offer a robust solution for SIP Trunking applications to the converged enterprise. Verscom offers operators a phased approach to expanding subscriber base and growing ARPU while minimizing upfront capital outlay.
Benefits of Verscom Enterprise SIP Trunking Solution
The Verscom SIP Trunking solution specifically allows providers to:
-
Offer secure SIP based VoIP services to the enterprise today including services such as VoIP VPNs and Customized Dial Plans
Cost-effectively enable IP-PBX interoperability, internetworking and manageability via the SIP Trunk
Offer flexibility for a growing enterprise with the use of Call Admission Control (CAC) and Session Admission Control (SAC) policies to handle the bandwidth utilization and session behavior over the SIP Trunk, as opposed to the rigid bundling structure of the PRI
Cost effectively expand services to branch offices of their multi-site global enterprise customer-base in any geographic market by reducing the costs of leased lines when sourced from a third-party provider
Provide enhanced management for multi-site enterprise customers with centralized network management of highly sophisticated & easily customizable VPN policies
Protect enterprise voice network and perform topology hiding against any such malicious threats.
Provide service specific QoS and SLA Assurance to enterprises relying greatly on quality of its voice communications by ensuring IP voice meeting the PSTN quality end-to-end
Aggregate CDRs for accurate accounting by the collection and normalization of CDRs across a number of network elements
Develop targeted service bundles including Presence and conferencing services to meet enterprise productivity needs
