Recently I’ve installed the newest Asterisk 1.6.2.6.
I dealt with Asterisk few times in past but never focused on QoS
capability. What I found interesting is that in sip.conf there are
fields for setting ToS field (with default values provided):
Even those parameters are named ToS they actually set DSCP. It might be misleading, because ToS it is full byte, whilst DSCP is a 6-bits part of ToS field.
- tos_sip=cs3 (SIP signalling messages)
- tos_audio=ef (RTP audio)
- tos_video=af41 (RTP video)
- tos_text=af41 (RTP text)
Even those parameters are named ToS they actually set DSCP. It might be misleading, because ToS it is full byte, whilst DSCP is a 6-bits part of ToS field.
