WatchGuard FireBox X Edge - SIP calls

Posted on 2012-08-28

I have a WatchGuard FireBox X 10E Edge firewall.  It's running OS build 178688.  I have a few SIP phones that I'm registering to a remote SIP server.  The phones register but I cannot make outbound calls.  I tried a outbound SIP proxy but something just isn't correct.  Any ideas?  I tried a software phone app and SIP phones and all get the same symptoms.

    Are doing static NAT; can you try 1-1 NAT instead.

    Thank you.

    I'm referring to outbound calls.. My SIP server is remote and not behind the firebox.  I disabled the SIP proxie and it seems to be working.  Still waiting for end users to make more calls.

    When using a SonicWall FireBox X 10E firewall there was no need to enable SIP proxy when remote extensions are behind the firewall...  SIP calls are sent/received without this.
