The only place you do NOT need igmp-query is point to point routed interfaces in the path that the multicast will take. Or any interface where there will be no users doing igmp joins/leaves.

Dennis & Christopher,
Thanks for the replies. Would I want igmp query-enable on the vlan with my phones as well?

Joshua,
You need IGMP as Dennis stated.
Set igmp enable <VID> <—All VLANs that will have clients/servers/or in path
Set igmp query-enable <VID> <— Only VLANs with Client/servers
I think you need to fix your “group mask” as well:
ip pim rp-candidate 10.205.1.1 224.0.0.0 255.0.0.0
Do you actually need that many multicast groups?
Regards,
Chris

Subject: [enterasys] Multicast config
I'm trying to configure PIM-SM on a Enterasys N7 so Multicast traffic can route from a server hanging off the N7 to a Vlan Trunk going to a Cisco 3750 where some phones are located.
I was just wondering if I could have another pair of eyes look at my config because it's not currently working. This is what I have, please tell me if I'm missing anything.
interface vlan 5 *** this is the vlan our computers sit on. It's here because it's in the trunk going to the 3750
ip address 10.205.1.1 255.255.248.0
ip pim sparse-mode
interface vlan 10 *** this is the vlan our phones are on
ip address 10.210.1.1 255.255.248.0
ip pim sparse-mode
interface vlan 20 *** this is where the server is hanging off
ip address 10.220.1.1 255.255.248.0
ip pim sparse-mode
ip pim bsr-candidate vlan 5
ip pim rp-candidate 10.205.1.1 224.0.0.0 224.0.0.0
