Media for Vonage and DSL on same phone line?

Vonage and DSL on same phone line?

I'm considering switching to Vonage, and I'm trying to think how best I might install it. I'd be getting DSL at the same time, and I was wondering if it is possible to use the following setup.

basically, the dsl and vonage box are plugged into the same phone filter. The dsl would loop into the Vonage box, then back into the same filter, thus the same phone jack. I'm probably not making much sense, but would this work?

Thanks ahead of time.
