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. -Eric
