Help required with Voice lab

christophermann
Level 1
Level 1

I wonder if somebody could solve this mystery for me. I am attempting to set up a Voice Home lab,but have run into an issue at the first hurdle

i have a 2950 12 port switch, that i have set up voice and data vlans on ( see config below) with int fa0/9 set as a trunk.

i also have a 2801 router set as the DHCP router and set as router on a stick to route between the two vlans ( see configs below)

i also have CUCM installed on a dell pc running on VMware. (the inferace for CUCM has an ip address of 192.168.1.14) and the physical interface on the pc is 192.168.1.16.

i also have a 7960 ip phone and cisco ip communicator to start things off with.

the problem i have is that the phone is unable to register at this time with CUCM.

As the it stands at the moment i am able to ping CUCM from the router, however i am unable to ping the router from the switch, and this is where i think the issue lies as there doesnt seem to be an connectivity between the phone and CUCM.

The phone and pc seem to be getting to the DHCP ok as they both have allocated the correct addresses from the address pools set up on the router.

I have torn this down several times now over the last couple of months but am still unable to get any further.

Any assistance that could be provided would be welcomed...i will keep trying..

Kind regards

Chris

SO, what IP address is the phone getting? Is the getting TFTP option?

I see that on the switch you defined Vlan1 interface with subnet that overlaps with vlan10, it appears you want to use VLAN 10 as your native VLAN and not VLAN1, you may also want to defined interface vlan 50 on your switch with proper ip address and vlan helper.

Also, in your switch config I dont see VLAN 10 and 50 defined.

Chris,

thanks for your reply. Are you saying make vlan 10 the native vlan?

i have created the vlans 10 and 50 and are present when i show vlan brief?

Just as an asside, if i plug the phone into int fa/12 on the swith it gets a data ip address (192.168.1.12) and registers with CUCM on vlan 1

could you explain what you mean by defining vlan 10 and 50?
