Phone Registration Site-to-Site VPN

Unanswered Question
Aug 7th, 2008

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 have this problem too.
