Frequently Asked Questions >
Birmingham Telecom are a customer focused provider who are experts in business SIP Phone Lines and Cloud Hosted VoIP Telephone Systems
Get in touch with our team to discuss how upgrading to SIP Phone Lines can benefit your business. SIP is replacing ISDN and PSTN by 2025 so if you have not done so already, it is good practice to find out what options you have before the switch off deadline.
Yes. One of the benefits of SIP Phone Lines 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 telephone lines are 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 phone lines 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 phone lines 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 Telephone Lines 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.
