Hello,
For the Cisco QOS:
Based on a Cisco Router all you need is a simple
access-list.
class-map match-any voip-class
match ip rtp 10001 9999
match access-group 150
!
!
policy-map voip-policy
class voip-class
priority xxx (in Kbits)
access-list 150 permit udp any any eq
5060
access-list 150 permit udp any any eq
4569
Voila!

Objet : [asterisk-users] Setting QOS settings in asterisk and/or CentOS?
How would I go
about setting the TOS bit to "RTP IP TOS Byte: 18 (hex)" for SIP and IAX traffic at the asterisk
server?
Also,
IP Type of Service
RTP IP TOS Byte: 18 (hex)
Silence Suppression
Mute Mode: On, UDP keep-alive every 10 seconds
G.711 Voice Activity Detection: Off
Codec Preferences
G.711u: 1 (Highest priority)
G.711a: 2
Do you have a quick
reference on how to configure a Cisco switch to prioritize SIP
traffic?
I check in various
Cisco docs, and there are so many references, and none of them seem to relate
directly to using the TOS bit for QOS.
I am looking into using the TOS bit because that is the only
method that my SIP devices use. (Citel Handset
Gateway)

Thank You,
