ephone 1
mac-address 8478.ACC6.958A
button 1:1  
paging-dn 86 unicast

ephone 2
mac-address 5475.D02A.F36E
button 1:2 
paging-dn 86 unicast 


ephone 3
mac-address 8478.ACC6.997E
button 1:3

My problem is simple,when i use to dial on page number as 1234 ,its working with all connected page-dn's,After disconnect from page service  some of telephones(6921) are not getting the dial tone ,even can't call internally or simply say phone get hang.does any one face this issue so far.please check my check above config & let me know your suggestion here!!!!

As i can see the ip phones and the cme in different subnets

 

What is your default gateway here?

Core Switch maybe

If so, configure multicast routing between vlans to route the paging packets

Under both vlan interfaces in the core switch add this command:

ip pim sparse-dense-mode

 

also add this command in the configuration mode:

ip multicast-routing

why are you using unicast here?

the paging-dn command should use multicast,

did you try it?
