The lack of sufficient connectivity to signal ringing suggests taking a 
peek with wireshark may be fruitful as well as reviewing the configuration 
of the endpoints.

Can you check the web page on the phones to confirm the IP addresses and 
netmasks are as expected? (What you think your configuration does is less 
important than what the phone thinks it does.)

I recently broke a lot of things between my office and my home when I 
decided to split 192.168.0.0 with a 255.255.255.128 net mask.

I also recently broke a working configuration by running Asterisk and 
OpenSIPS on 5060. The phones would ring but could not answer. Lost a lot 
of time until I started confirming the really basic stuff and entered 
'sudo netstat -a -n -p | grep 5060'
