Dlink DVG-2001S VoIP Phone Adapte, brand new, factory unlocked.
The DVG-2001S converts any existing analog (cord or cordless) telephone into an IP Phone. Also by plugging in a FAX machine, the DVG-2001S will enable users to send and receive fax the same way as a traditional analog telephone line.
The DVG-2001S supports the SIP protocol, which is widely deployed by VoIP providers on the market. It also supports the most popular audio CODECs to ensure compatibility and voice quality.
The DVG-2001S VoIP Phone Adapter comes with one FXS port to connect to the existing analog telephone and one Fast Ethernet port to connect to the broadband router.
With a built-in secured provisioning feature, VoIP service providers can configure service settings such as a server address, CODEC and STUN settings via HTTPS/TFTP directly to the DVG-2001S.
For additional security, all of the configuration settings are encrypted. Only the VoIP service providers/resellers with the authenticated password and user name can access it.
The DVG-2001S features both the VAD (Voice Activity Detection) and CNG (Comfort Noise Generation) to reduce the bandwidth consumption and to sustain voice quality.
The DVG-2001S VoIP Phone Adapter has a built-in QoS setting to provide voice priority in IP networks and prevent dropped calls. By delivering a consistent quality of service, resellers will avoid having frustrated customers from switching to another VoIP service provider.
