OK, that part's done:
interface GigabitEthernet0/0
  description To USCTSTVSW01 Port g1/0/1
  no ip address
  no ip unreachables
  no ip proxy-arp
  duplex auto
  speed auto
  media-type rj45
  no keepalive
  no mop enabled
!
interface GigabitEthernet0/0.10
  encapsulation dot1Q 10
  ip address 10.255.3.1 255.255.255.0
  ip pim sparse-dense-mode
  h323-gateway voip bind srcaddr 10.255.3.1
!
interface GigabitEthernet0/0.999
  encapsulation dot1Q 999
  ip address 10.244.3.1 255.255.255.0
  ip pim sparse-dense-mode


However, still nothing. :(

Is there anything that needs to be done on the switch side?  The

"int vlan 10" and "int vlan 999" commands on the 3750's don't seem to 
have any commands relating to multicast.

I also don't seem to have any multicast commands available on the 
switches in a global sense.  Wrong IOS?  Or am I thinking this wrong?

Right now, only the speaker that's on the 10.255.3 network gets the 
page, but ideally I get this working "right" and speakers can live on 
the 10.244.3.0/24 network.
