SIP Trunking - Making better connections

SIP trunk provider - Six Degrees Group knows that a full-scale migration to SIP trunking is inevitable. Developments such as BT’s 21CN (21st Century Network) demonstrate that the SIP trunking migration is already underway. This is combined with carrier network upgrades that result in VoIP being used for all backhaul and core network voice transit to mean that numbers of TDM analogue and digital voice trunks are in decline.

Many of our MPLS customers have quality of service capable WAN links between their sites and already use their WAN for inter-site voice over IP. For those customers, adoption of SIP trunking is the next logical stage in their evolution as they already have a network that is voice ready. Along similar lines, almost every new connectivity customer of Six Degrees Group SIP trunk provider is either undertaking a limited-scale SIP trunking rollout or is planning on doing so, even if they are not yet considering a complete ISDN replacement.

SIP Trunking

With our experience in SIP trunking, we also recognise that the death knell for traditional voice has been prematurely rung before, meaning that direct voice or WLR is still the preferred option for many customers. For those customers, SIP trunking presents a compelling back-up service to traditional voice lines. Our SIP trunk services can be provisioned using your existing Internet access or IP-VPN connections or via a dedicated line.

A full or partial move to SIP – e.g. using a blend of ISDN and SIP trunks in a hybrid configuration – can be undertaken to allow customers to improve their inbound capabilities. SIP trunking breaks the link between the DDI and the line connected to the local exchange, allowing you to be more flexible in how you handle calls. This is especially compelling for companies who need to deal with constant changes in their business. SIP trunking allows capacity to be dynamically added or reduced, depending on call levels, during the course of a business year.

In short, SIP trunking will reduce line charges, will offer new business continuity options, improves on inbound call handling, offers new options for burstable trunks and is easier for businesses to manage through simple online management portals.
