Are You Ready for the PSTN/ISDN 2025 Switch Off?

With the convergence of voice and data, BT Openreach announced in April 2017 that they will phase out their existing copper wire PSTN telephone network by 2025. Anyone currently using PSTN- or ISDN-based services will have to switch to another service before then.

Despite this deadline, a recent survey by National Business Communications revealed that 70% of UK businesses are still using landlines and an astonishing 24% are not even aware of BT Openreach’s plan to discontinue traditional copper wire telephone services.

What Is the Alternative?

Session Initiation Protocol (SIP) technology bridges the gap between traditional telephony and digital voice-over-IP (VoIP). SIP Trunking allows you to make and receive calls using the SIP protocol over an Internet connection (IP line). Because SIP Trunking utilizes existing telephone equipment/infrastructure, it is a reliable and flexible alternative for businesses looking to switch from ISDN (or PSTN) to VoIP. Although not every business has the same PBX, SIP Trunking offers a solution for every business thanks to its many possible configurations.

  • SIP Trunking in conjunction with an on-premises PBX: If a VoIP PBX is installed on site, a SIP trunk is required to connect to the outside world.
  • SIP Trunking in conjunction with an on-premises ISDN exchange: Connect the exchange directly via an ISDN-to-SIP gateway on a fixed-line network
  • SIP Trunking as a hybrid solution: installing a SIP trunk in combination with a Gateway on a legacy PBX. This allows all calls to be processed over the new IP lines.

Why You Should Consider SIP Trunking

One Day Turnaround for Remote Calls

Title : One Day Turnaround for Remote Calls
textonbutton :
Requirebutton : No
A professional association sent 250 employees to work at home during the pandemic. Unfortunately, what happened was more like pandemonium. Because all employee direct numbers had to be forwarded to ring a new number, the association was using two paths for every call and quickly ran out of call paths. The result was constant busy signals for members and employees. The association reached out to Black Box on a Thursday afternoon, by Friday, we provided 10 “test” SIP call paths over the customer’s existing Dedicated Internet access. We also arranged a call between vendor engineering, the association, and the SIP service provider. By Monday, we were able to activate 150 SIP call paths. In a matter of hours, the client was able to place calls using the new SIP call paths. The client was happy, and we concentrated months of work into days.
