OBI 110 to OBI 110

[fonemax]

I'm new to the world of OBI.

I'm trying to extend a dialtone from a telephone system to a distant telephone.

E.G.
Ext 120 ( pots dt ) is connected to an OBI 110 and at the other end a pots phone is connected to the other OBI 110.

When I dial 120 from anywhere within the system, I want the pots phone to ring.
If I lift the handset at the other end, I want to draw system dialtone, to be able to dial other ext in the system.

I've added the devices in OBItalk.
Now what

Thanks
