Most legacy phone systems ARE NOT compatible with VoIP or IP

Upgrading will help you!

SIP Phone Lines and Cloud Hosted Phone Systems are now rapidly replacing older, traditional ISDN and PSTN services. 

All of our solutions are sold UK wide where they have proven to be ultra reliable and both cheaper and more flexible than traditional the digital or analogue phone lines that are gradually being made obsolete.  There is no reason why you shouldn’t consider upgrading now to maximise both savings and benefits.
