Until recently, NocTel recommended the use of Cisco SPA line VoIP adapters for integrating legacy paging and intercom systems. However, some of the most cost effective models are approaching end of life and will not have manufacturer support for issues. This also means eventually production is likely to cease making procurement of the devices harder and more expensive. To remedy this, NocTel evaluated and successfully integrated the Obihai OBI110 FXO VoIP adapter for the same purpose with a lower price per unit (for the OBI110 model).
