David,
AVLinkPro has always worked great in our Simpl integrations.
I haven't tried it with CH yet, but they have a product geared specifically to CH.
Also, they just released a "SIPAHOY" bundle that adds even more CH functionallity.
I never really liked the "form factor" of the 2N gate solutions, so AVLinkPro helps to bridge other systems into Crestron's implementation of SIP.
We use the Holovision door-station products because they can be customized to meet the client's needs with very elegant metal finishes.
Then, AVLinkPro just helps everything work together, including SIP phones.
I'm very curious how it works with Crestron Home, though.
Good luck,
Brian
