Zultys Technologies has announced the release of four VoIP phones to complement its existing range.
All four phones feature: call control using SIP to permit interoperability with a broad range of SIP products; full duplex speaker phone with good speech quality using a custom-designed acoustic chamber for the speaker and advanced acoustic echo cancellation; jitter buffer; 3.5 mm headset jack (pink and green) that permits the use of standard headsets; 20 keys and 15 buttons to ensure functions are easily accessible; 128 bit AES encryption; four ethernet ports with true line rate switch; four call appearances that permit four separate calls or a conference with up to five parties; large backlit LCD that can be adjusted; and management by TFTP or HTTP file download or HTTP browser.
The ZIP 4x4L and ZIP 4x5L have graphical monochrome LCDs while the ZIP 4x4B and ZIP 4x5B have graphical colour LCDs, a USB port and Bluetooth to support wireless headsets and the BTC conference phone.
The ZIP 4x4L is designed for business owners that want a fully functional phone for the office. The ZIP 4x5L is designed for the remote worker because it includes a complete router with VPN, NAT, firewall and DHCP server. This phone also has an analog port to provide local PSTN telephony service allowing a remote worker to publish a local phone number and dial emergency numbers. It can be plugged into the broadband device to provide IP telephony, access to network resources and the full functionality of the PBX at the headquarters, to a user away from the main office.
