I’ve had a lot of troubles getting Sipgate SIP connections working with Trixbox. I’ve searched loads of forums and they all give opposing opinions of what works and what doesn’t. In my case I’ve found them mostly not to work. However, now I’ve got my SIP connection working (at least for incoming, I’ve not tested outgoing).

Here’s my configuration. In the trunks page every box is empty except for under Outgoing Settings I’ve got:

Trunk Name set to an appropriate name

PEER Details set to

allow=alaw&ulaw&g729&gsm&slinear
bindaddr=0.0.0.0
context=from-trunk
disable=all
fromdomain=sipgate.co.uk
fromuser=YOUR_USERNAME
host=sipgate.co.uk
insecure=very
nat=no
port=5060
qualify=no
secret=YOUR_SECRET
srvlookup=yes
type=friend
username=YOUR_USERNAME

and Register String set to :

YOUR_USERNAME:YOUR_SECRET@sipgate.co.uk/YOUR USERNAME

Hope this helps someone as it took me ages to work this out.

After spending ages playing around with both Parallels and VMWare on OS X I’ve decided it’s probably easier if I get a local copy of Asterisk working rather than running it on a virtual machine. With the project I’m working on I need access to the files that Asterisk has created and was having problems getting the files between the the virtual machine and my Mac.

I’ll assume you’ve got the Macports system installed (if you haven’t you can find out how to do so here). However there’s no port for Asterisk, so I’ve created one for Asterisk 1.4. To get it all running, you have to:-

• Checkout my ports directory: svn co http://svn.cumu.li/ports
• Edit the file /opt/local/etc/macports/sources.conf add the line file:///Users/anthony/develop/ports/ to the bottom
• Do a sudo port selfupdate
• Do a sudo port install asterisk14 – this should install Asterisk
• Do a sudo launchctl load -w /Library/LaunchDaemons/org.macports.asterisk14.plist to start Asterisk and enable it on boot

When the port is installed you will have two extensions, 101 which gets directed to agi://127.0.0.1 and an IAX2 extension on 102 (password 102) – this is for you to test the line. A good IAX client is Loudhush. In the Loudhush preferences create a new account with localhost as the address and 102 as the username and password. When you save this Loudhush should say your registration has been accepted.

You can monitor what’s going on by using the Asterisk console. In a terminal just type sudo asterisk -rvvv and you should get you an Asterisk console. If you try to call line 101 from Loudhush you should see Connect to 'agi://127.0.0.1/' failed: Broken pipe on the console.

Hurrah! The Asterisk stuff should now be working! You can use this to do work with the Telegraph and Adhearsion Ruby/Rails telephony packages.
