Landlines and Calls

Providing fixed landlines, calls & services to your business.

As a business, it is vital that you make the best choices when investing in the latest technologies, ensuring that you not only plan for the future, but maximise your potential today.

We offer packages with standard analogue telephone lines, suitable for smaller businesses, to ISDN lines for SME’s or mid-size businesses. If you are looking to take advantage of the latest technologies, we install SIP channels, enabling any number of lines provisioned over your broadband, enabling you to connect 8+ channels, allowing for multiple calls, as well as QOS (Quality of Service) on our dedicated leased lines.

You can expect significant savings against your current bill, plus exceptional service from a trusted telecoms company. Transfer your business lines and calls to Wellwood and we will help you find the best solution to suit your business requirements. We have our own engineering department and our focus is on service rather than sales. 

What type of phone line is available and how will it benefit your business?


Standard Public Telephone Lines that can be used for voice, fax, alarm, lift lines and broadband connections. Also supports Multi-Line Facility with multiple sockets.


 These Digital lines can be either ISDN 2 which provides 2 channels per circuit, or ISDN 30 which provides 8-30 Channels per Circuit. These also support Direct Dial Numbers.


SIP is a cost-effective and flexible alternative to ISDN for your inbound and outbound voice calls. 

How does it work?

Our SIP channels connect your site directly into the network via an IP connection to carry and terminate your inbound and outbound voice calls across the public telephone network. Our SIP Channels provide a highly-flexible alternative to ISDN and are compatible with all IP telephone system brands in the UK market, giving you peace of mind that your telephone system hardware works with the network service. Compared to ISDN, SIP Channels are cheaper on a per-channel basis and more flexible in terms of what telephone numbers you can have and the locations in which you can have them. In addition, they are quicker to install and offer a robust business continuity service that ensures your business never loses any calls. Our service can support connections ranging from two channels for businesses with small telephone systems, with no limit on the number of channels that can be supported for large enterprises.




Flexibility with phone numbers

SIP trunking enables you to move office and keep the same geographic number without any ongoing call-forwarding costs or those associated with producing new company stationery.


Business continuity

If your office has to be temporarily relocated in an emergency, this can be achieved quickly and cost-effectively with SIP trunking to keep your business working.


Save money

IP connectivity costs less than ISDN with lower call costs, free internal calls between extensions and offices and lower line rental costs for multi-sites. Also, no expensive call forwarding costs are required should you relocate or need to divert calls in the event of a disaster.


Line rationalisation

For businesses with multiple sites, SIP trunking provides the opportunity for line rationalisation and reduces the number of PBXs you need to maintain – while retaining full control of the numbers associated with your business.



SIP trunking provides a phone service that will cope with any situation and give you business-grade resilience for your telephony. Whether you need to keep your business running in a disaster or emergency or you need to load balance your calls between sites during peak hours, SIP trunking delivers.
