[Voll, Scott]

Could the mail server be marking your smtp traffic?

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!
