Make sure you are using the right settings in Torch....
and you can always sort on the DSCP Marks.
You should see something like in the attached picture...

I’ve been trying to see DSCP marks in torch on our CRR’s… can’t
seem to see anything in the interface. I’m going to try a packet
capture and view in Wireshark.
Thanks for your input.
Cheers,

Andreas,
Yes, here is the logic....
PBX should mark packets correctly (RTP packets as well as SIP
signaling... for packets going towards to the CPE).
Phone CPE should mark packets correctly... (for packets going to
the PBX)
Routers typically are not constrained on their pipes, so traffic
flows well.
Unless you are using some sort of queues to restrict traffic
flow.... then you have to make sure that dscp/qos marked traffic
flows with priority.
Most radio's will respect DSCP/QoS marks and allocate priority
accordingly... (check with your radio mfg / firmware version,
config etc).
BTW you can easily see the DSCP/QoS marks if you use TORCH on the
MT, it is real time.... :)

Faisal,
So the packets should still contain DSCP tags regardless of
layer2 or layer3?
Sounds like I will need to do some packet captures.
Cheers,

Hi Andreas,
in our network, we handle this as follows:-
1) we make sure that the PBX is marking the packets with the
DSCP tags correctly.
2) we make sure that the phone/iad are marking the packets
with DSCP tags correctly.
3) we make sure that the Radios (AP & CPE) are using firmware
that respects the DSCP Tags, and provides them with
appropriate priority
4) we don't do anything on our routers (in our network). if
we have to, the only thing we do on the customer router
(Dmarc) is to make sure that the dscp tags are correct.
And this works very well for us.
Regards.

Hello All!
We have about 90 sites primarily with CCR’s of various
flavours. We have yet to implement any type of QOS for
our VOIP..but we are starting to feel some quality pain
with a couple of our “ON NET” PBX/SIP products.
I have been reading about using mangle rules to mark
connections and then packets, then setting up a QUEUE
tree in MT where the packet marks are prioritized. We
are fully routed with no layer 2 / bridging. I’m
wondering if I can accomplish the same thing by just
identifying the IP of my Multi-Tenant PBX box and any
traffic moving to and from…and prioritizing it as 1.
Secondly, do I have to do this on every single router on
my network?
OR Is it a better practice to IDENTIFY DCSP or TOS, mark
and prioritize that instead. Just looking for the best
way to unify this across my network.
Anyone have examples? Many of the examples I have seen
really relate to SOHO type situations…. We are talking
much larger here. Most of my transport is 200Mbps to
10Gbps between sites.
