Does the voice stream of a Jabber client have the same QoS markings as a phone like the 7900 series or is the voice best effort over an on-premise network?

Assuming Jabber for Windows since you didn't specify. The client will attempt to set DSCP markings; however, Windows policy may prevent this from getting passed to the network. You may need to create a Group Policy that allows the application to set QoS. Additionally, the access-layer switch port needs to accept DSCP markings from the data VLAN. Historically (i.e. auto qos) this has not been the case.
Additionally, Cisco is adding support for MediaNet Services Interface which - if installed on the endpoint and configured in the network - allows Jabber, WebEx, or other MediaNet-aware applications to explictily tell the network about the traffic flows and the treatment they need. This should end up being far more precise than blindly trusting or policing traffic on the data VLAN.
PS- There is a dedicated Jabber space here on the communities.

Hi
I can share with for example if your question regarding Cisco jabber for windows.
1-First question , you have to ask your self which ports which Jabber used to established please find the below link which includes all ports
http://www.cisco.com/en/US/docs/voice_ip_comm/jabber/Windows/9_0_1/b_jabber_win_icg_chapter_011.html
based on that you have to do an access list which capture all the above ports. i created QOS which can capture Jabber traffic and applied to F0/1 which connected to a PC which have jabber.
mls qos
mls qos map cos-dscp 0 8 16 24 32 46 48 56
ip access-list extended jabber_ports
permit tcp any any eq 80
permit tcp any any eq 443
permit tcp any any eq 993
permit tcp any any eq 7993
permit tcp any any eq 143
permit tcp any any eq 389
permit tcp any any eq 2748
permit tcp any any eq 5060
permit udp any any eq 5060
permit udp any any eq 69
and so on match the ports based on your usage for jabber
class-map match-any Jabber-sig
match access-group name jabber_ports
ip access-list extended udp
permit udp any any range 16384 16424
class-map match-any Jabber-udp
match access-group name udp
policy-map JAPPER
class Jabber-udp
set dscp ef
class Jabber-sig
set dscp cs3
class class-default
interface f0/1
mls qos trust dscp
service policy input JAPPER
Thank you

Terry,
There are two ways documented here..
1. Deploy with Cisco Media Services Interface
2. Set DSCP values in IP headers of RTP media packets
Read the documentation and it will give you a better understanding..
Islam,
Jabber signalling traffic should not be calssiffied as EF. Thats RTP traffic. Signalling should be classified as CS3 and RTP as EF

Hello
Yes sir , you are completely true.Please check my configuration again , RTP which represnet (UDP access list) is mapped to EF and signal (jabber ports) mapped to CS3 .I am sure from my configuration now , maybe i changed the classes names by mistake.
Thank you
