[cisco-voip] Remote office phone connectivity

[Kádár Zsolt]

Try to use random-detect option in class-default instead of fair-queue.

HELP!

I need some QOS and VOICE experts here.

I just got done putting out a major fire.

Our mail server in our Hub office (CALLMANAGER LOCATION) started sending out MASSIVE amounts of email to our remote offices.  Bandwidth consumption on the WAN links between the HUB and remote offices shot up to 99.9%/7%.

Our remote users had complaints of phones rebooting, calls not going through or being dropped, not being able to make outbound calls (through their local PRI), but I could call them and talk w/o any problem.

I don't understand.  I do have QOS setup Prioritizing VOICE and VOICE Control packets and I'm sure it's right (see QOS config below)

I throttled SMTP at my hub router and all the phones started working fine.

I've maxed out the interface in the past and tested the phone w/o any problem.

All ideas and suggestions are welcome.  Thanks!
