A cordless SIP and analogue DECT phone with up to 6 handsets.
Easily configured with most SIP providers although its codec support does not include iLBC so it does not work well with low bandwidth connections on Gizmo.
Codecs include G711a, G711u, G726 and G729 but not iLBC.
The default line can be set to either SIP or analogue. The non-default line is used if you hold the green call button down for 2 or more seconds to make the call.
Nice quality hardware.
