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® CX600 IP phone delivers all the features included in Microsoft® Lync™ environments to provide a cost-effective, mainstream desktop phone. The client does not require a PC to make calls, or gain access to personal contact information, call logs, calendar information, or other advanced features.Polycom CX600 (2200-15987-025)
