[asterisk-users] Setting QOS settings in asterisk and/or CentOS?

[Redouane Doumer]

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!
 
Redouane

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, 
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)
 
ref:
QOS settings from Citel Handset Gateway:
Handset Gateway - QoS Configuration

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
 
 

Thank You,
