The basic IP settings are made here.

TOS

The TOS (Type of Service) byte inside the IP header is used for prioritization of packets inside the network. The device allows some packets to be marked as higher priority. The TOS values for this purpose are configured here.

TOS Priority RTP-Data Configuration of the TOS value for media (e.g. voice) packets. The value 0x10 is used as standard. Consequently, voice data receives priority forwarding.
TOS Priority Signaling Configuration of the TOS value for Signaling (e.g. H.323 or SIP) packets.

RTP Port range

First UDP RTP port / numbers of port: This entry restricts the range of ports in which UDP RTP voice data (User Datagram Protocol Real-time Transport Protocol) is received for H.323 or SIP calls. The port range 16384 to 32767 is used as standard. 128 ports are the smallest range. For a voice connection, an RTP port and an RTCP port are used.

UDP NAT port range

First UDP NAT port / numbers of port: This entry restricts the range of ports that may use UDP NAT data (Network Address Translation).
