A Telekom SIP Trunk is a type of Virtual Private Network (VPN) service that allows businesses to connect their on-premise phone systems to the public switched telephone network (PSTN) over the internet. This provides businesses with a number of benefits, including cost savings, increased flexibility, and improved reliability.
SIP trunks are becoming increasingly popular as businesses look for ways to reduce their telecommunications costs. Traditional analog phone lines are expensive to install and maintain, and they can be inflexible and unreliable. SIP trunks, on the other hand, are much more affordable and they offer a number of features that can improve business communications.
