Smart IP Systems
What is SIP?
SIP trunking is a service that connects your PBX telephone system to the PSTN with an IP network instead of an ISDN.
SIP (Session Initiation Protocol) is the standard for VoIP (Voice-over-internet-protocol) services, enabling voice systems to be provided over the internet instead of over traditional telephone lines. This allows businesses to migrate from having different systems for their voice and data networks to having one that does both.
Trunking is a dedicated method of allowing different telephones to share a set number of lines.
With this knowledge and understanding of the basic features and benefits we're sure all our clients will install a SIP Line System.
