Hi Moussa,

Can you help us understand where the phones are connected and what is the exact topology? Do you want to configure IP phones connected to switch in two different VLAN's? If that is what you want then you can create two Voice VLAN on the switch, create a trunk with the CME router allowing traffic for both VLAN and configure intervlan routing on it.

You may refer to the link below:

hi Aseem, thanks for your repley

but the problem is in source-address ip under "voice register global" which one i should put because i have 2 vlans

!

g0/0.1

encapsulation dot1q 60

ip address 100.30.60.1 255.255.255.0

!

g0/0.2

encapsulation dot1q 70

ip address 100.30.70.1 255.255.255.0

!

ip dhcp pool voice-60

network 100.30.60.0 255.255.255.0

default router 100.30.60.1

option 150 ip 100.30.60.1

!

ip dhcp pool voice-70

network 100.30.70.0 255.255.255.0

default router 100.30.70.1

option 150 ip 100.30.70.1

Hi,

Best would would be to configure a loopback interface on the CME and use that address as the source address.

thanks Aseem,

in my case the configuration of loopback interface is like that:

!

interface loopback 0

ip address x.x.x.x

!

am i right?

Aseem Anand · ‎10-11-2016

Hi,

Yes, you are correct! You need to make sure you can ping the loopback IP from switch as well try to ping one of the phone's from both the subnet using the source address of loopback to make sure connectivity is bidirectional.

Ping X.X.X.X source loopback0

hi Aseem,

thanks

Hi Moussa,

If you are not able to ping the loopback IP address from your PC then you need to check the routing. Can you ping the two IP addresses "100.30.60.1" & "100.30.70.1" from your PC as well as from the switch?

Also do a trace route.
