Cost Effective POTS Replacement in Existing VoIP Networks

Cost Effective POTS Replacement in Existing VoIP Networks

Analogue phone lines on copper wires have been available for decades. There are many systems implemented on this service, including fax, monitored alarm systems, remote management access to IT equipment and SCADA systems. Mobile telephony and mobile data is ubiquitous and is the current standard for remote data access, making copper phone lines redundant.
Since existing copper lines are losing market share to mobile, they are becoming more expensive to operate, maintain and deploy. Hence, providers are now motivated to decommission their analogue phone lines to customer sites. For many customers, migration to mobile only is a difficult problem, and an interim solution is preferable to large-scale redesign of functioning networks.
