Simple, cost effective, scalable phone lines for your business.
SIP Telephone Lines are virtual telephone lines, created over your internet connection and work with a traditional IP Telephone System to replace your legacy Analogue or ISDN telephone lines.
In most cases, SIP Telephone Lines are most cost effective way to upgrade from ISDN or PSTN technology where you will also benefit from having all of your UK telephone calls included at no additional cost.
SIP Telephone Lines can be ordered with as little as 1 channel and can be immediately scaled up (or down) in line with demand and without the need for additional physical line installation.
