The Voice Call Manager marks SIP and RTP packets with DiffServ CodePoints (DSCP), which enables other hardware to recognize and prioritize these packets.
LANconfig: Voice Call Manager / Advanced
WEBconfig: LCOS menu tree / Setup / Voice Call Manager / General
- SIP DiffServ CodePoint (DSCP)
This defines which DiffServ CodePoints (DSCP) the SIP packets (for call
signaling) are to be marked with.
Possible values:
- BE, CS-0, CS-1, CS-2, CS-3, CS-4, CS-5, CS-6, CS-7, AF-11, AF-12, AF-13, AF-21, AF-22, AF-23, AF-31, AF-32, AF-33, AF-41, AF-42, AF-43, EF
- CS-1
Anmerkung: The option CS-1 is actually outdated now, but it is set as the default value to ensure backwards compatibility. Common values for modern VoIP installations are CS-3, AF-31 or AF-41. We recommend using CS-3, one of the most widespread settings on the market. - RTP DiffServ CodePoint (DSCP)
This defines which DiffServ CodePoints (DSCP) the RTP packets (voice
data stream) are to be marked with.
Possible values:
- BE, CS-0, CS-1, CS-2, CS-3, CS-4, CS-5, CS-6, CS-7, AF-11, AF-12, AF-13, AF-21, AF-22, AF-23, AF-31, AF-32, AF-33, AF-41, AF-42, AF-43, EF
- EF
Anmerkung: With DSCP set to BE or CS-0 the packets are sent unmarked. Further information about DiffServ CodePoints is available in the Reference Manual under the section "QoS".
