Dear All
I had created a DMVPN between 4 diifreent site Hub-Spoke topology, i am using 3com ip phones but i am facing one issue, the issue is i am not able to join confrence (Multiasting) between the spokes, from the hub i can hear both the spoke, but the spoke cannot hear each other. i had enabled ip multicating and Ip pim Saprese-dense mode, the ip telephone comunication between the hub-spoke and spoke-spoke is working, but when i join all in confrence i.e. HUB-Spoke-Spoke it is not working, the hub can hear both but the spoke cannot hear each other.
Please help, its very urgent, thanks in advance

it sounds tunneling issue i mean when the tunnel in use between the spokes and the hub no comunication happen between the spokes
i havnt faced isues like this
however try to make another tunnel between the spokes and the hub deffrent IPs
and make a static route for packed distend from spok to another spok to go through the new tunnel
but i am not sure
like u hav ealready tunnel0 make tunnel 1
and static route
i route x.x.x.x x.x.x.x interface tunnel 1
where x.x.x.x/x your spoke network
do it on both sides
Good luck

Thx for your response Marwanshawi
I sort out the issue, the issue was with Maping, for confrencing of ip phone work between the hub, i had to create the static map for each spoke on the other spoke, i used command
#ip nhrp map "spoke tunnel address" "spoke Public Address"
ip nhrp map multicast "spoke public Address"
After doing this i was able to see all spoke as each other PIM neibhours.
And multicast calls were establish between all sites.
Once again thx for your response.
Have a Good Day.

Can you post you DMVPN specific information? Under the HUB tunnel, do you have plit tunneling turned off? That is the most common reason I have seen for lack of spoke to spoke communication.
Furthermore, do you have it set up for dynamic spoke to spoke (bypass HUB) communication?
