[cisco-voip] Phone to phone call doesn't work?

[Scott Voll]

I believe I have some kind of a network mapping issue.  eg. a ARP table
screwed up some where or a CEF table, or an MLS table.

How do I change that on a 4506.  on a 6509 I think I used to use sh ip mls
something, but the 4506 doesn't have sh ip mls......

Thanks

Scott
