voice vlan not register phone

[sarimirfan]

any one can help me (voice vlan)

its  just a home lab

 I have call manager 8.6 (VMware version) running with cisco 2811 router and cisco 2950 switch. On switch configuration I have Data and Vice Vlan (router on stick).

Router is register with CM, data and voice pool seems to be working fine b/c I can ping form any ware, but only thing cisco phone 7960 not register if is part of my voice Vlan. Phone are pick configuration from voice vlan  on the phone screen stuck on (configuration cm list)

but if phone is not part of my voice Vlan its work fine

What should I need to done to resolved my problem

thanks

Hi

1) Can you ping the voice VLAN interface on the switch/router from CUCM? If not, then your routing is not corret

2) Are you assigning option 150 to both the VLANs (voice/data) via DHCP?

3) Are you assigning DNS servers via DHCP on both VLANs, and can the CUCM server names (as shown in System/Servers in ccmadmin) be resolved via DNS?

thank you for replying quickly

let me apply everything you tell me then i will back to you

1) yes I can ping vlan from switch/router, but not form cucm. from cucm I can ping switch/router.

I can not ping to any DHCP pool from cucm

2)option 150 I just assign to voice vlan dhcp.

3) Yes i used  DNS server 4.2.2.2 just to voice vlan, i don't assign cucm server name

Hi

If you can't ping the VVLAN switch interface from CUCM:

Check that CUCM has a default GW set to a device that has a route to the VVLAN.

Check that 'ip routing' is enabled on the switch, if the switch is doing L3 routing.

hi

I cant ping VVLAN/ Data Valn from CUCM. all other ip I can ping

where can I find default GW ?

I have L2 switch 2950

thank you

Hi

If you have a L2 switch, then you will need a router to route packets between the voice and data VLANs.

Everything in the VVLAN should use the VVLAN interface of the router as the default gateway.

Everything in the Data VLAN should use the Data VLAN interface of the router as the default gateway.

Seems to be routing issue. 

Make sure you have the following configured:

Switch:

vlan 10

name data

vlan 20

name voice

vlan 30

name server

interface f0/24

switchport trunk encapsulation dot1q

switchport mode trunk

Router:

interface f0/1

no shutdown

interface f0/1.10

encapsulation dot1q 10

ip address 10.0.0.1 255.0.0.0

interface f0/1.20

encapsulation dot1q 20

ip address 20.0.0.1 255.0.0.0

interface f0/1.30

encapsulation dot1q 30

ip address 30.0.0.1 255.0.0.0

I have assumed the IP addresses. Its just a sample configuration

Hi,

I have gone through your routers config. You have created DHCP on your router itself. There is no need for ip helper address under each interface that you have configured.

Please post your switch config again, I am not able to view your config properly
