The Importance of VoIP & SIP Security

VoIP (Voice over Internet Protocol) provides a cost-effective way for businesses to communicate. Cloud-hosted VoIP is even more convenient and removes the need for on-premises PBX hardware. Your VoIP platform of choice, whether on-premises or hosted, can be connected to the wider public switched telephone network via an SIP (Session Initiation Protocol) trunk.

What To Do After The End of ISDN

BT Wholesale is stopping the purchase of new ISDN and PSTN circuits. This is the first step toward an eventual shut down of these telephone systems in 2025.

The end of ISDN will force organisations currently utilising ISDN to move entirely to VoIP telecoms solutions before 2025. At Carden Telecoms we are encouraging our customers to stay ahead of the curve by switching to a VoIP phone system.
