The basic IP settings are made here.
- ToS Priority: Configuration of the ToS (Type of Service) field for voice packets. The value 0x10 is used as standard. Consequently, voice data receives priority forwarding.
- 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.
See also the notes contained in Appendix B: "Troubleshooting", section "Port settings in respect of NAT and firewalls". - First UDP NAT port / numbers of port: This entry restricts the range of ports that may use UDP NAT data (Network Address Translation).
