hi i am curious to why i receive "high traffic try again later" message on the phones when i dial out. can anybody tell me how to troubleshoot this? i have no idea where to start, but i think it would be in the service parameters somewhere. i am not sure. thanks

Cisco Call Manager, or some other brand/software (alcatel, etc)? I'm not the one who handles the phones here, but you could check your call statistics. Maybe your bandwidth consumed by the phones is too high for your internet connection. Our phones are set to auto adjust to available bandwidth, not sure if you can set it otherwise. What's the phone model? Do you have a support contract?

no i do not have support really.
my net tech thinks we should implement ip cef on the switch ports. I also think i should lower the bandwidth rating on the device pool to 8kb/s in the Call Manager. I get the error on 7940s, 7962s, and 7965s.

I agree, try lowering the bandwidth rating first and see what that gets you. I'll ask the phone guy when I get to work and see what he says.

my net tech wants to try something tonight and see if that works. i forgot what he said though lol. i was out of it.

i need a good call manager book to read and learn.
does anybody have any recommendations? I want to be a callmanager wizard. or router wizard. i know most of the callmanager, but i do not know what specific functions does and how to make it into exactly what i want. i have cut sheets i go by
thanks
