Guys, Quick question. On the wiki I noticed that examples 3, 4, and 5 all use escaped parentheses, whereas examples 1 and 2 do not. Example 3: <extension name="Test3"> <condition field="destination_number" expression="^00\(.+\)$"> <action application="bridge" data="sofia/profilename/$1@192.168.2.2"/> </condition> </extension> Example 2: <extension name="Test2"> <condition field="network_addr" expression="^192\.168\.1\.1$"/> <condition field="destination_number" expression="^1(\d+)$"> <action application="bridge" data="sofia/profilename/$0@192.168.2.2"/> </condition> </extension> (Note the expressions following the 'destination_number' fields.) Is this a typo? I just want to be sure that I am reading this correctly. Seeing escaped parens in a PCRE tells me that the expression is attempting to match literal paren characters. Additionally, using ".+" might not be correct here, either. It means, "match one or more of any character, maximal." If I'm reading the author's intentions correctly, in example 3 he wants to capture the digits after the 00, so in the case of "00123456789" he wants $1 populated with "123456789". Correct me if I'm wrong, but shouldn't the condition and expression look like this? <condition field="destination_number" expression="^00(\d+)$"> Here the expression is saying, "Match a string of all digits beginning with two zeroes; capture the digits following the two zeroes and store them in $1." I didn't want to change the documentation without a second opinion. (FYI, I can't test it right now b/c I don't have a running FS system at the moment...) Thanks, MC
