your system for the registration at the SIP Server

your Audio transmission.
STUN Server Parameters
• If you use a STUN Server, please enter the IP Address here.
LAN Parameters
• Decoder Buffer Mode: The Audio transmission over IP networks via
UDP

requires a buffer in the decoder due to the different transmission
times of the individual IP packets within the network (Jitter). By default
the buffer mode should be set to Automatic. To be on the safe side, the au-
tomatic mode selects a larger buffer than it might be required.
If you know the parameters of your network provider, you can select a
Fixed buffer. In this way, the total delay of an Audio transmission can be
optimised.
