### Description According to [RFC4594](https://datatracker.ietf.org/doc/html/rfc4594#page-19) ``` ------------------------------------------------------------------ | Service | DSCP | DSCP | Application | | Class Name | Name | Value | Examples | |===============+=========+=============+==========================| |Network Control| CS6 | 110000 | Network routing | |---------------+---------+-------------+--------------------------| | Telephony | EF | 101110 | IP Telephony bearer | |---------------+---------+-------------+--------------------------| | Signaling | CS5 | 101000 | IP Telephony signaling | |---------------+---------+-------------+--------------------------| ``` Kamailio should relay SIP messages with DCSP value `CS5` To set this value I can use in config file ``` tos=0xA0 ``` This works as expected But when I use text form this does not work ``` tos=IPTOS_PREC_CRITIC_ECP ``` `IPTOS_PREC_CRITIC_ECP` defined in the `/usr/include/linux/ip.h` as ``` #define IPTOS_PREC_CRITIC_ECP 0xa0 ``` I expect both forms `0xA0` and `IPTOS_PREC_CRITIC_ECP` should works.
