      Hello,

      Got a real doozy of a question (seems so simple at first) :). I have a Cisco 7940 (Running SIP) behind a PFSense (1.2.3-RC3) box. I am unable to dial OUT or IN. (my VOIP providers details are correct im
      fairly sure :)) I have been unable to figure this one out from the forums I have been on and a lot of different 'techie' friends help, so I'm a bit at my wits end.
      I am using Mynetfone www.mynetfone.com.au directly from the phone. I have a feeling its something to do with NAT?
      I can dump the cisco's debug and any other information if anyone has any ideas.

      Thanks for your time guys!

      Mike.

        You don't want or need port forwards for a phone.

        Your problem is probably one of these 3:

          I have exactly the same setup, and I use NAT. The phones use the WAN IP and handles the rest by themselves. Absolutely no problem.

            Thanks for your advice. I am looking into your proposed 3 problems and I will report back.

            Kind regards,

            Mike.

              I don't know what a Cisco 7940 is. Perhaps my experience described in http://forum.pfsense.org/index.php/topic,18204.0.html might be helpful.

                It's a standalone telephone well suited for Cisco Callmanager LAN setups. It can be converted to SIP very easily and does a great job as a SIP phone. I use no other phone at the office and back home, and PFSense is very easy to setup so the phone works.

                  thanks for the continued interest in my success guys.
                  I'm afraid I still can't call in or out its very frustrating :(
                  I have a lot of debug output / configs and whatnot just not really sure where to start.
                  If anyones interested in my ramblings let me know and I'll post some output :)
                  edit: I actually have a deep-seated suspicion that my modem is to blame (DSL 502-T)
                  Further edit:
                  I placed my phone in front of PFSense and Behind the modem, result: instant call in and out.
                  The problem clearly lies with my PFSense configuration and/or its interaction with the modem.

                    Why not use the switch feature in the phone then???

                    But PFsense is very easy with 7940…. If you know teamviewer I can give you a quick hand via live messenger...

                      I'm not familiar with that software sorry. In Q1 next year we will be upgrading to bridged PPOE + Cisco router which should eliminate any complications, post-firewall
                      (our network diverges into two separate networks behind the modem currently) However if you wouldn't mind helping me figure out whats wrong with the phone when
                      behind the firewall drop me a PM and i'll pass you the details.

                      Mike.
