Hi,
On 26xx with 12.1(17) is:
dial-peer voice x voip
destination-pattern xxx
ip precedence 5
session target ipv4:xxx.xxx.xxx.xxx
> While you COULD do this, voice is typically looked at to be treated as
> dscp EF (46), which equates to IP prec 5, low delay, high reliability
> when you look at the bits as legacy RFC791 would interpret them.
>
> If you have diff-serv capable devices all through your network and
> create a QoS policy across all of them to make some sense out of things,
> then there's no saying you can't do 63 though! There are just presumed
> values (EF, Afxx) for drop thresholds and whatnot along the way.
>
> Also, signaling is typically treated with lower priority, your call
> setup is TCP anyway.
