Thank for your answer.

Yes you have right.

But the T0 line coming in another "room" than Cisco UC560.

I have two switch (support vlan) in each room.

And I cannot (or I wrong me) make T0 through VLANs.

It's for that I must use a patton gateway for convert T0 to SIP and send SIP data to a dedicated VLAN.

Thank you for your help,

Stephane.

You can extend the BRI S/T bus over ethernet wiring. I takes two pairs per circuit, so you can take two circuits on a single cable.

Or move the UC500 to the place where the circuit is installed.

Both solutions are easier and will give better results than using an external gateway,

Sorry i dont give many details.
I cannot install Cisco UC in the another room it's a problem of responsibility (not a technical problem but an administrative problem).
And because this config dont want help me, I have only one fiber channel for link my room to another t0 room. Vlan data/admin/VoIP are in the trunk.

Thank you,
Stephane.
