ToS/DiffServ

This sub-page is used to configure the Type-of-Service/Diffserv byte values,
which are to be used in the IP header of all transmitted SIP signalling packets
and RTP packets. The ToS/DiffServ byte values are entered as two-digit
hexadecimal values. If no special ToS/DiffServ value is to be used for a
particular traffic type, enter “00” or leave the setting empty.
Press “Save ToS/DiffServ Settings” to save these new settings.
