I have a Cisco 4507 switch with IP Phones connected to it. On IP Phones Port, I have command enabled, "AUTO QOS VOIP CISCO-PHONE"
4507 port 5/18 connects to 2821 FE0/0 router via DOT1Q trunk to carry both voice and data traffic.
On 4507 5/18 port I enabled, "AUTO QOS VOIP TRUST"
I think swithch is now ready to priroitize Voice Traffic. What kind of QOS I need at the 2821 router. 2821 has (2) PRI T1 connects to PSTN, and (2) T1 MLPPP connects to the Internet. Client has a branch locations that they will connect via VPN. My first priority to make sure that 911 calls routed very quickly as it will since it will go through the PSTN, and I have "AUTO QOS VOIP TRUST' enabled on a Switch port, but when the calls come back or 911 calls back the router's FE0/0 is sharing the traffic between voice and data so what is recommended to priortize voice traffic back from the Router to the Switch.
Thanks,
