[Asterisk-Users] More beginner questions

Sat Dec 20 11:47:03 MST 2003

Once the connection is made between your * and FWD, your * passes it off
so its really just a connection between your soft-phone and FWD.  So,
your soft-phone needs to be properly NATed, and the appropriate ports TO
your soft-phone need to be opened.  Each SIP phone will attempt to use
different ports (usually UDP), so you need to find out what those ports
are and make sure they are opened and NATed to your soft-phone.  I've
never gotten it to work because I wasn't willing to open up my
soft-phone that much to the Internet.

I have experienced, however, a great deal of luck using IAX to
communicate between two (actually three) * systems in different
locations.  The only port that needs to be opened is UDP 5036 for IAX,
or UDP 4569 for IAX2.

Good luck!

Subject: [Asterisk-Users] More beginner questions

Using DIAX softphone which seems to be working OK can get to VM/echotest
etc in the demo context

Am trying to setup FWD but get the following problems

Can hear it ringing when dialing FWD no 612 for time.  Connects but no
sound from remote end.

Does anyone have any suggestions.

Softphone on 192.168.0.2 asterisk on 192.168.0.3 Netgear RP114 doing NAT
to the internet port 5060 being forwarded to the asterisk box.

This seems to be quite useful software but it's frustratingly difficult
to get running.
