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.
The Polycom® SoundPoint® IP 321 and 331 are two-line SIP phones that deliver superb sound quality as well as a wide range of supported business telephony features. This phone has a single 10/100 Ethernet port and is designed for common areas, such as lobbies, hallways, and break rooms.
