My assumption is that as long as you have your COS - DSCP mapping in place
that you can do either.
My preference is to do the DSCP values due to the granularity as well as
similarity to what I normally do at customer sites (so it's more of a habit

COS does exist in the 1q header in the 1p field, however the pc nic (most)
has the ability to add this to the frame. (should see "qos packet scheduler"

since we're using IP Blue in the lab, i wanted to download it and play with
it a bit.
problem is that the demo is 20 minutes and it resets.
anyone know of a way around it short of shelling out the $600 for the 5
licenses I would need??
just trying to make things easier.

Its my understanding that the CoS value is set in the 802.1p field
within an 802.1q tag. Therefore, in order to set a CoS value you need
have an 802.1q trunk. So a PC would not be able to set a CoS value,
unless its uplink was an 802.1q trunk port, rather than an access
port.
So if the PC can't s
Unless I misunderstand you, COS is applied to a packet and does not require
a 1q trunk. The connection between the pc and the phone is not 1q usually.
Just the connection between the phone and the switch. Most PC nic's can be
setup to mark it's packets with a cos value and effectively take priority
So, I have a gateway (2811) and a gatekeeper (2851)...
I have an FXS on the 2811 and I want to register it to the GK using
the 4-digit extension...
How?
When I try register e164 ont he dial peer it says it has to be a full
e.164 number...

JD,
Cisco's website states the "switchport priority extend cos 0" command
instructs the phone to override the priority value from the attached
device.
"Configuring the Priority of Incoming Data Frames
You can connect a PC or other data device to a Cisco IP Phone port. To
process tagged data traff
Right, but since CoS only exists on the dot1q trunk frame, how could
the PC even set any CoS value?

Wow... i stand corrected. I always thought that it's the other way around.
Thanks for the info.

Hmm,
Proctorlabs support forum (www.proctorlabs.com/forum) you should find their
pstn cloud configuration there!

Always do a google search, too :-)

Your definition is reversed. The command "switchport priority extend cos 0"
does NOT allow the IP phone to reset the COS value received from the PC. It's
the opposite of that. That command is FOR the switch to reset the COS value
received from ANY device connected on the IP phone to a COS va
Darren,
Why dont you try something like this
Using 4 digits extension in this case:
voice translation-rule 1
rule 1 /^222333\(4...\)/ /\1/
rule 2 /^\(4...\)$/ /222333\1/
voice translation-profile pstn
translate calling 1
translate called 1
translate redirect-called 1
And apply it:

Cos is recommended (per the QoS SRND) for any dot1q trunk...
However, my concern is not the switch, but the voice gateway's Fast
Ethernet to the switch... Do we need to trust outbound (switch to
gateway), and inbound (on the gateway side...)

dialplan-pattern appears to be a trap... so, you may want to stay away
from it... I would probably stick with outbound translation rules (to
expand 4 digit to full e.164 to route via the PSTN in SRST/WAN
down...)

Well, I do have subinterfaces and it is a dot1q trunk to the

Hi Everyone,
I see that the standard practice on a switchport is to configure
"switchport priority extend cos 0" in order to allow the ip phone to
reset the cos value received from the PC to 0.
My question is how would a PC ever set a "CoS" value if the link
between the ip phone and the PC is not
OK, so we set the switch ports to trust CoS on the dot1q trunk from
phone to switch... are these then trusted from that point on, or do we
need to trust them elsewhere as well?
Do we need to add any config to the voice gateways to trust the CoS
coming from the switches?
Jonathan
When in SRST H323 fallback ..is it best practice to voice translation on
the voice ports or use the dialplan-pattern command under
call-manager-fallback?
Im confused about how the incoming phone call is translated to the SRST
phone dnany help appreciated.
Example
I have an inbound DID
