Steve thank you for the pointers, you got me going in the right direction.

Here is what I came up with (so far it seems to work).

<extension name="Line 2(6820)" continue="true">

<condition field="source" expression="mod_freetdm"/>

<condition field="${channel_name}" expression="^(FreeTDM/2:2/)$">

<action application="info"/>

<action application="set" data="domain_name=$${domain}"/>

<action application="set" data="transfer_ringback=$${us-ring}"/>

<action application="answer"/>

<action application="transfer" data="2000"/>

</condition>

</extension>

All I have to do is modify the second number in the expression. 2:3 line three, 2:4 line four etc.
