MGCP QoS Config for 2600 @ Branch Edge

[joshw]

Can anyone post a sample config for a 2600 running as an MGCP gateway with 2 FXS analog ports. I can't seem to find anything that shows how this is properly done.

Joshua, See this link for the answer to your request. The document references a VG200, but, will be the same for a 2600.

Thanks for the URL, actually I posted wrong, I actually need a sample config that shows the gateway configured with QoS. I have utilized a CBWFQ config and it seems to work but would just like to make sure.

Sorry for the delay.

This is what I've found.

MGCP

"...Cisco CallManager by default uses a DSCP value of 26 (AF31) to backhaul all signaling (TCP or UDP), and can be changed within the Cisco CallManager Administration web pages by going to the Service Parameters for the Cisco CallManager service, and selecting IpTosCm2Dvce, although it is strongly recommended that you do not change this value.

When configuring QoS, remember that the Cisco CallManager (the "Call Agent" in MGCP terminology) and end devices use UDP port 2427 and TCP port 2428 respectively."

So, prioritizing UDP 2427 and TCP 2428.
