I am unsure about which configs are sufficient for implementing QoS on 2 2600 series routers over a 2MB serial link. On one side is the IP pbx and there are up to 6 IP phones plugged into a switch on the other side.
We are using a non-cisco VoIP product using g.729. From what I can see all I need to do is put the following commands on the serial interface's of both routers (where "70" referring to 70Kbps should be enough for 6 calls?):
ip rtp header-compression
ip rtp reserve 16384 100 70
I have a few questions:
Is this right?
What about the Ethernet interfaces? Do they need commands to prioritise the traffic on the ethernet interface?
We have looked at the traffic used on the phones and they use ports around 7000-8000 for actual voice packets...but the advice I read says that the command (ip rtp reserve 16384 100 70) covers it all (16384 +100)???
Thanks for any help in advance.
