Important notice the unit can receive and accept incoming IP calls even when its current network interface is not Ethernet IP provided it not already busy with an established link Network quality setting Depending on the quality of service provided on the network especially its jitter performance it is possible to change the stability latency compromise used by the SCOOPY For this purpose a setting is available in the menu Setup Network Ethernet Parameter Network Quality Three choices are proposed e HIGH suitable for a good quality and low jitter network latency is minimal but the codec will have little tolerance to possible jitter e MIDDLE intermediate and default setting suitable for a moderate transmission jitter e LOW to be preferred when the network has low QoS especially for residential ADSL lines This setting ensures a safer operation at the cost of a high latency On a LAN and or private network with a controlled quality the HIGH quality setting is recommended as it yields minimum latency On the contrary it should be avoided for a link via the Internet as it can only tolerate a low jitter One solution can be to start with a MIDDLE setting and switch to the LOW setting if too much audio disturbance is heard Quick redialing Once a remote device has already been called it is easy to recall it press the key then you can scroll through the call
