Hi,
I have a call manager connected to switch with three VLANS configured, one voice vlan and two data vlan,
int f0/1-2
switchport mode access
switchport access VLAN 200
int f0/3-23
switchport mode access
switchport access VLAN 300
switchport voice VLAN 100
intf0/24
switchport mode trunk
switchport trunk encapsulation dot1q
int g0/0.100
encapsulation dot1q 100
ip address 172.100.1.1 255.255.255.0
int g0/0.200
encapsulation dot1q 100
ip address 172.200.1.1 255.255.255.0
int g0/0.300
encapsulation dot1q 100
ip address 172.300.1.1 255.255.255.0
I am able to access the call manager if I assign it an IP under data VLAN range, but if I assign IP under voice VLAN( 172.100.1.0/24 ) i am not able to access the call manager, If i assign an IP address to the call manager under voice VLAN I am not able to ping even the default gateway 172.100.1.1
What may be the issue.

encapsulation dot1q 200
ip address 172.200.1.1 255.255.255.0

Hi,
Thanks for your help, I have tried the same config which you have provided, please refer the config given by me, please help me to figure why I am not able to access the call manger as per the scenario mentioned by me.

Hi Mario/Muammer,
Thank you very much for your support, I got the issue fixed, I forgot the concept that Data devices does not do VLAN tagging, so when I assigned an IP in the voice VLAN range to the call manager, the switch tagged it with data VLAN, as both the VLANS were enabled on that switch, now I have cleared the problem.

Raja,
You need to make sure that the "switchport access VLAN100" is set on that port that is connected to the CM, if you want the CM to have an IP on the voice subnet.
