asterisk users - Feb 2015 - ports, routers and firewalls

I just want to make a SIP call from 192.168.1.3 to 192.168.1.4; or not 
even a call.  Ring?  Beep?  Ping?  Some sort of "hello world"
connection.

192.168.1.1      netgear router
192.168.1.2      asterisk (vicidial)
192.168.1.3      ubuntu client
192.168.1.4      mac OSX client (not shown)

Do I have a firewall problem which would impact a soft phone from 
establishing a connection?
