Fixed Lines, Calls & SIP
Analogue phone lines still have their uses either to support a broadband service, alarm line or fax however the days of ISDN services are numbered. You may aleady be aware that BT will be switching off the ISDN network in 2025, therefore if your fixed line telephony contracts are coming up for renewal, now is the time to start looking at migrating to SIP technology.
So what is SIP?
SIP Trunking is a form of VoIP telephony and now represent a very viable alternative to ISDN. SIP allows the running of voice calls over an internet connection instead of a traditional phone line. SIP trunks now represent a very viable and popular alternative to ISDN services as data connectivity increases in quality and prices reduce. SIP trunks are ideal for keeping business phone numbers when relocating, connecting multi-site phone systems together or businesses looking to have a disaster recovery solution.
If you need the flexibility and control of your own phone system – and either already have a phone system or are happy to buy, run and manage the phone system yourself – SIP Trunks are the right choice for you.
