Hosted IP Voice

The SWAN Hosted IP Voice service provides the flexibility to transition your existing voice telephony services onto our fully-managed Cisco Hosted Collaboration Solution (HCS). The SWAN Hosted IP Voice Service is already resiliently connected to the SWAN network.

The HCS platforms are hosted in two UK data centres with resilient connectivity to the SWAN Network, enabling easy, secure and cost-effective access for SWAN customers. Connectivity to the Public Switched Telephone Network (PSTN) is also directly integrated using the SWAN SIP Trunk service.

Service Overview

This platform and the related services have been developed to allow organisations with 500 or more users to provide the same range of advanced voice and collaboration services across their whole estate, regardless of their location. This even includes off-net options for home users or remote sites which may not at the initial stage have direct connectivity to the SWAN WAN. Our Solution Architects and teams will review your existing services, advising you on potential solutions and transition strategies. These solutions can include professional services and consultancy; covering all aspects from initial scoping, through set-up and migration to supplement your own skills and resources. In addition, the service includes ongoing maintenance and management updates to ensure the central multi-tenant platform remains up to date with Cisco releases.
