SIP Phone Lines

Simple, cost effective, scalable phone lines to meet the needs of your business.

Our SIP Telephone Lines are virtual voice lines, created over your internet connection and work with any modern telephone system to replace your current analogue or ISDN telephone lines.

SIP phone lines are now most cost effective way to upgrade from ISDN or PSTN technology where you will also benefit from having all of your UK telephone calls included at no additional cost.

SIP telephone lines can be ordered to carry as little as a single concurrent call but can be immediately scaled up in line with demand and without the need for additional physical line installation.  There are no limits to the number of calls that can be carried out over SIP phone lines.

An amazing, professional, above and beyond service. We have recently moved over to Birmingham Telecom from another 3CX supplier. Where our old suppliers were terrible and misleading, Birmingham Telecom has been extremely helpful and forthcoming with any issues or charges that we would incur. Can highly recommend this company, massive thanks to Dan and Lee who have helped us out so much.

Our Company, The Phoenix Pattern & Tool Co Ltd, have been customers of Birmingham Telecom since they started out. They have replaced our phone system 3 times, recently bringing us into the 21st Century. The 3CX system that we have now is user friendly and the app enables working from home much more convenient. Special thanks to Andy for always getting the right product to suit us and Shaun for the time and effort put in with us during and after the installation, Dan and Lee for attention given quickly to any of our queries. A great job, I have no hesitation recommending Birmingham Telecom.

We have just signed to transfer over to Birmingham Telecom in the last week, the transition is not due to take place for a few weeks, but our phone and internet line was cut last week. This company setup an app-based phone system within a few hours getting us back up and running and receiving the calls. Amazing effort and great first impressions. Very positive, knowledgeable, and supportive staff.

Yes. One of the benefits of SIP Trunking and moving your call management online, is that you can keep your number when you move office, or even out of the area. This is because your phone number will work over the internet and not via a fixed line running into a building.

No, SIP phone lines simply remove the requirement for ISDN or PSTN telephone lines and are simply a more efficient, more cost effective and more reliable solution to replace this old technology.

You will still need a phone system that is compatible with SIP phone lines however, the good news is that we will be involved from start to finish, providing you with all the help and advice you need.

Yes. SIP is easy to integrate with existing business telephone systems both physical and in the cloud.

Our SIP trunks are fully compatible with all IP enabled phone systems including software based solutions such as 3CX, Microsoft Teams etc.

Integrating these systems with our SIP trunks allows you to improve both your internal and external communications and reduce your costs significantly.

Because your business’ calls will run over the internet it means you can integrate SIP over your existing internet connection.

This means you don’t need to invest in any additional hardware and it also reduces the costs of your network because you don’t need to establish new fixed lines.

With SIP phone lines you can have an unlimited number of channels that you can add to your call network. This means you can easily scale up the number of concurrent calls you can make or receive and reduce the number of SIP channels during quieter periods.

Yes. You can even use your SIP Trunking with existing ISDN connections. If something goes wrong or your organisation experiences an emergency, you can reroute your calls to another location using the same number until the problem is fixed.
