8el Introduces SIP Trunking

Reading based VoIP and data communications provider 8el is formally launching its SIP (Session Internet Protocol) trunking solution saying this enables VoIP customers to reduce the costs associated with telephony, while providing greater flexibility over numbering and scalability.

The addition of SIP trunking brings some of the cost benefits available through VoIP to both IP- enabled and non-IP enabled PABXs.

Says Justin Hamilton-Martin, managing director of 8el, “SIP trunking is a relatively new direction and not many operators are offering it yet, largely because ensuring service quality depends on having the right support infrastructure in place – which we do. We’ve engineered a SIP trunking solution that meets our customers’ high service quality expectations and it has already been ‘tried and tested’, with some of our existing customers already experiencing the benefits, not least of which is reduced costs associated with ISDN line rental.”

Other benefits include scalability – whether up or down – on a ‘per channel’ basis. SIP trunking is also not dependent on geography, so the network will route calls to wherever the recipient is located, without creating any call-forwarding costs. DDI numbers can also be allocated quickly and cost effectively and calls between SIP trunking users in the same network are free.

Installing SIP trunking simply involves adding an extra IP interface into the customer’s data network and this is part of the ‘all in one’ service that 8el provides. As is the case with any other 8el service, 24/7 network monitoring is also available through our managed SIP trunk service. There are two main forms of SIP trunking: ‘managed’ and ‘unmanaged’.

Says Justin Hamilton-Martin, “With a managed service, users access our SIP based network via an on-site IP or ISDN based device, to create a SIP link to our core. In addition, to ensure security is maintained for customers, we authenticate by IP address, route, user name and password via our Session Border Controllers.”
