[cisco-voip] sccp ip precedence

[Jake Rybak]

Thanks. I just wanted to be 100% positive that it is changing the voice
stream and not signaling. I guess I could have just captured the packets but
I wasn't in place that it was possible.

As you know, MGCP and H323 you can choose signaling or media. 

So being registered to a CM 3.3, the CM service parameter would override
this anyway? Not that you would want to.

Yes, that's obviously a typo, if this is your first day with Cisco docs then
you might want to get used to it. If maybe you can give an idea of what
you're trying to accomplish then maybe we can try and give you some
guidance. By default at least in the Cisco world you can expect voice
control to be tagged as IPPrec of 3 (AF31 or CS3) and media (rtp) as IP Prec
5 (EF). Unless you have a reason to mess with these values then why bother?
Again without knowing what you're trying to accomplish then it makes it
difficult to give you any sort of advice. BTW, IP Prec is old school, the
rest of the world uses DSCP?
