Hello,

I want to use different VLAN with my Call Manager and my IPPhone.

In the catalyst, define voice vlan for my ipphone,

in the router I define the sub-interface for the CUCM and for the Voice VLAN.


Is it possible that phone can function ?

Thank you very much,


If i understand, if an office have voice VLAN.

I define switchport voice vlan in the catalyst,

After, I define a trunk with the command switchport voice vlan,

After, I connect this trunk in my router,

And in my router there is a vlan interface for the voice vlan, and there is another interface for CUCM VLAN.



Is it like that ?

Thank you,


And about the VLAN,

I've asked in this forum about the audio ip address in the softphone, but no response yet.


Can you explain about the audio ip address?


How to use the audio ip address in the ipcommunicator.


Can I use the VLAN Voice with the Softphone.

'cause i've already tagged my port with switchport voice vlan.


thank you
