VoIP User Connects 14 Million BT Customers To iNUM PDF Print

VoipUser.org, the largest open-source VoIP network, has announced the interconnection of British Telecom 0870 range numbers to the VoIP peering iNUM network.

"VoIP remains restricted by the lack of interconnection between networks," said Dean Elwood, founder of VoIP User. "By interconnecting to the BT 0870 range, we have enabled cross-network calling for 14 million users which is free of charge at off-peak times. What we have achieved today is the extension of our service into a new network of over a million VoIP users".

British Telecom Plc, the UK's largest telecom provider, announced that from 16th January 2009 it will make 0870 numbers free to call to subscribers on their Anytime call plan.

John Peter, managing Director of BT's Consumer Business, said in a Press Release on Thursday "All of our 14 million Anytime customers have free calls included in their package and now all 14 million have free calls to 0870 at times that fit with their calling plan, which is something not offered by any of our competitors."

Ian Plain, of technical consultancy cyber-cottage.co.uk, who architected the system for VoIP User, said "we created a mapping service for the 0870 iNUM interconnect. The system is accessed by users dialling 08700 68 58 48 from a BT landline and entering an iNUM number to contact. Details can also be stored meaning that the caller only ever has to enter the iNUM number to contact once."

2 1/2 years and still going strong PDF Print

In late 2005 We we approached to replace an aging Panasonic system for a British Public School.
The driving force for moving to voip was that the site was spread over a wide area and different buildings and to provide telephones to the remote buildings would prove too expensive.
The system was replaced with a central Asterisk server with nearly 80 extensions. The core LAN was upgraded to Netgear Layer 3 switches with Powerdsine POE midspans.
The remote buildings added extra complexity as one was on the other side of a public road.

Solicitors Group PDF Print

We were approached to provide a Voip solution for a London Solicitors. They were moving from a Single office to two offices in different parts of the city.

At the Primary office we installed an Asterisk server that was connected to the ISDN30e link where all DDI numbers were delivered for both sites. This site also had its own VOip connection as well

At the main site the operators were based using the Asternic FlashOsPanel for displaying extension status for both sites.

A key feature of the system was to provide a flexible system for out of hours callers to contact the duty Solicitor. This was provided so that callers on calling out of hours  can leave a message for the next day or press an option to contact the Duty solicitor. The Duty solicitor can call into the system and change the contact number at will if for example they are busy with a client.

A SIP trunk connected both sites together over a 20Meg link that was used for both voice and data.

Gompels Healthcare PDF Print

Gompels Healthcare are a Wiltshire based mail-order  company supplying healthcare and cleaning products to the health care industry such as Nitrile Gloves and Disposable aprons.

We were contacted as they were in the process of moving to a larger office and distribution centre close to their existing office. The move was to be phased with staff to be based at both sites for a period and the added complication of the line plant not being available at the new site till after they  planned to have moved in.

Man In The Middle Server, What does he mean I hear you ask?

Well its the best term for it, as it describes what it is and does. Basicly we have an Asterisk Server sitting in between the incoming lines and the main  PBX. Idealy We would have liked to replace the existing PBX but in some cases this just isnt possible and we have to accept this.
