The SWAN SIP Trunk service is both a commercial and operationally compelling option for users of the SWAN network. The network already supports Voice classes of service for SIP Voice: in the first instance it is simply a case of checking that suitable bandwidth is available to support your SIP Channel requirements. A guideline table is available to illustrate the amount of SIP Channels supportable on each of the SWAN catalogue. If you are happy with that, a Solution Architects can then be engaged to help with any further qualification, including any resilience considerations. SWAN has resilient core network gateway connectivity at a Carrier level into several of the major UK Carriers. On receipt of details of any number ranges you wish to ‘port in’ and the amount of SIP trunk lines required, we will respond with a quote to illustrate the potential return on investment. A further simplification in using SWAN SIP Trunks is that you can port numbers in from any UK geographic location. This removes the need for local lines, to support regional numbers and instead provides the same connectivity via IP Handsets to those same sites. Service and support are simplified with the SWAN Service Desk able to take ownership and to triage issues across the combined WAN and IP Voice services.
