It is recommended to upgrade this Avaya Product soon.
This product uses IP lines and SIP services to transmit the voice through the internet connection to the other party (data over the signal connection). Teltek’s Nebulosity Cloud PBX and Stratus Cloud PBX are systems which provide this service. We also can adapt analog devices (like fax) to our VoIP system.
