I have a site to site VPN between two cisco firewalls. I'm trying to get an IP phone to register at the remote location with the Publisher at the home office. A desktop can ping the server from the remote end of the tunnel, but the phone does not register. The DHCP at the other end has been configured for option 150. Are there any ports that I have to open in order for this to work?

I would first make sure that the routing is correct. When you tested with the desktop from the remote office, did you make sure it had an ip address that was on the voice vlan?
