Anybody using Nortel IP telephony on Cisco switches? I've done several all-Cisco IPT installs but never using Nortel and unfortunately I can't find any docs on best practices for this hybrid setup, specifically the QOS differences.
According to CCO, "auto qos" is said to only work with Cisco phones but if the phones mark the packets the same way then I don't see why it would matter since the packets should be classified the same way by the switch and the switch queues used in the same manner.
The only difference I can find is that I should use the more generic "auto qos voip trust" option rather then specifying the "cisco-phone" option. Will this trust both 802.1p and DSCP values assigned by the phones? Or is it a one or the other situation?
If anybody has any thoughts or comments on this I would greatly appreciate it. Of course, I've been given almost no time before go-live to lab this up so I'm grasping for straws. ;-)
Thanks!
Rik
