Business Calls & Lines Packages

✓ Analogue Lines 

B4BC can deliver analogue lines which can be used for small telephone systems, and more commonly broadband.  An analogue line is a single copper cable that installed in your building by BT Openreach, and terminated on a BT phone socket. B4BC can also deliver Analogue multiline, so you can have more than one call on one telephone number, perfect for an office with multiple extensions.

✓ B4BC SIP Trunks

BT have recently announced they will be switching off the ISDN network, this means UK businesses will need to switch to VoIP services before then. B4BC SIP trunks are the future of communications.

✓ What are SIP trunks?

SIP trunks or SIP Lines connect phone calls using VoIP technology (Voice over internet protocol) via the internet. Phone numbers and DDI’s are linked these trunks, so people calling your phone number notice no difference to calling a traditional telephone line, often the call quality is vastly improved!


✓ ISDN Lines

B4BC ISDN uses digital technology to deliver telephone calls. We offer both ISDN2 (which comes in pairs) and is designed for smaller businesses, and ISDN30 (which has a minimum of 8 channels) and is aimed at larger businesses. Some of the main benefits of switching to ISDN are;

✓ Call Quality – Digital phone calls offer greater clarity and quality over traditional analogue lines.

✓ DDI’s (Direct Dial Inbound numbers) – If you have a busy office you can assign each individual theier own DDI number, so when someone calls in the call can be router directly to them through your PBX.

✓ Resilience – ISDN lines are more stable than normal analogue line, we can also run in depth diagnostics on ISDN channels.

✓ Multi Party Conferencing – ISDN lines are great for multi-party conference calling due to the clarity and speed of connection.

✓ Caller ID & Number Presentation – With B4BC ISDN you can present your phone number, and also track who is calling in. the number will be displayed using CLIP (Calling line identification presentation) or COLP (Connected line identification presentation)

Diane Illingworth, Crayford Greyhound, Ladbrokes

“I just wanted to say how thankful I am for all your help in getting our office telephone system back up and running after our continued problems with BT. The speed and level of service we have received from B4B has been outstanding, for us to be back up and running so quickly has saved our business a fortune in lost revenue".

Mark Comer, Maintenance 24/7

“I just wanted to thank you once again for all your hard work and help in setting up the new telephone system. I want you to know that your assistance has been appreciated. Please do not hesitate to pop in for a coffee or tea when you are in the area”!

Anna A Kouma, Migrant Legal Action

“It is so refreshing to have a telecoms company where you can put a face to a name, trust their advice, receive a consistent service and not get passed from one stranger to another. From day one, Freddie Hawker and his team have been incredible. Freddie and his team are always friendly, efficient and will go out of their way to help or solve a problem and most importantly provide a consistent telecoms and broadband service. When we risked going two weeks without internet in our office, B4BC went above and beyond their call of duty to give us internet during this period without any strings attached. I would highly recommend B4BC to any business”

Megan McCall, Psycle London
