I have a customer with 2 Aspires 7.32 with a couple of IP Phones that were working fine until the made some changes to the fire wall .The phones come up and are kind of half working the say "network busy" you can not make or recieve calls but they do show the extension number and when you call the extension it ring and you can see the caller id but when you answer the call you get a busy signal and the call drops

Any Thoughts
