Call routing

[dan@etrixs.co.uk]

Hi I'm struggling to understand the documentation so was hoping someone can help me.
I've installed YATE on ubuntu as default.  So I understand this is a simple sip server.
I've setup four users/extensions.

100
200
300
400

And they all work great.  They can all dial each other and have conversations.
Now my next step is to do the following

I want to change the line 100 so that it becomes an alias for my external voip provider (voip studio)

I've setup my voip account in accfile.conf and I can see from the logs that it's connected to my voip account successfully.

The problem comes when I try to setup the routing.... and I think it's because I don't understand what is happening.

Basically, I want the following to happen, if I dial a number on extension 100 I want it to use my Voip Provider.  If someone rings my voip external number then my extension 100 will ring.

So in regexroute.conf i've tried the following 2 expressions but neither seem to work.

^100$=line/100;line=voip_studio

or

^.*$=line/\0;line=voip_studio


Please can you help me solve this issue.

Configure regfile the have a route priority with a greater value then regexroute (this way regexroute will route first).
Avoid the same value: the order of handling will depend on module load order.

OR:

In preroute handler of regexroute change the called number and handle it in route:

[contexts]
${called}^100$=return;ORIG_CALLED=${called};CALL_TO_LINE=voip_studio;called

[default]
${CALL_TO_LINE}.=line/${ORIG_CALLED};line=${CALL_TO_LINE};called=${ORIG_CALLED}
