Problem Details

The innovaphone devices allow you to specify the IP v4 TOS header field value used for voice and signalling IP packets. The configured value directly maps to the the header field of the IP packets. The IP ToS header field in the innovaphone device configuration must be provided as hexadecimal value for the 8-bit ToS field of the IP packet. This article describes how to deduce correct hexadecimal values from DiffServ / DSCP values.
