NO. I encourage them (the clients)to utilize me, and refer all calls to me. Any calls from anything to do with promotion of the site are directed to me. Its all about me-me-me. and the service I give them.
I tell the clients that they can listen to the pitch if they want, but in most cases, I already have the background (and potential questions)to evaluate the call much more effectively than the client.
If the client insists on taking the calls, I ask them to conference me in - my relationship with most clients is strong enough that they know I am on their side, and I won't let them get talked into something they don't understand. And vice versa. If I think it is a good deal, we test it in most cases.
