1. Generally yes, this config is good enough for prioritizing voice traffic going out of Serial or Fast Ethernet interfaces. The only thing I would like to mention here is the ACL being used, generally I have seen the following ACL for Cisco Voice devices:
access-list 102 permit udp any any range 16384 32767
access-list 102 permit tcp any any eq 1720
(the above are actually the ports Cisco devices use.......1720 for call setup and range 16384 32767 for the RTP stream)
2. "Service-policy output" command should be on Dialer interface
3. For ATM interface, there is a difference in how QOS is applied. I am not an expert on ATM so I can only point you towards the document which explains it
Documents that should prove useful:
** Configuring CBWFQ and LLQ on MLPPP and Dialer Interfaces
hello, my name is michael and i'm trying to configure the same oqs setting as grunger106 i have cisco 887va.
I know this response was recorded a long time ago but still ask for your help.
I set grunger106 script above and i put Service-policy output" command on Dialer 0 interface but its still don"t work. i still have jitter and delays.
