Technically that is not a big issue, however I will explain it for the sake of discussion. The ^ and $ are "anchors" for the beginning and end of the string. Consider these patterns: \d (match a single digit) \d+ (match one or more digits) ^\d+ (match a string that begins with one or more digits) \d+$ (match a string that ends with one or more digits) ^\d+$ (match a string that contains only one or more digits) So, the pattern ^(\d+) literally means: "Match a string that begins with one or more digits and capture those digits into the variable $1." The only issue with not having a $ at the end of the pattern is that there could be other stuff in the string after the digits. For example, these strings would all match the pattern "^(\d+)": 1x 43abc 12345abcd 998877LA_LA_LA_WHATEVER 18005551212!hoohah If you added the $ at the end of the pattern then none of the above strings would match. Hope that makes sense.... -MC On Tue, Feb 7, 2012 at 11:46 AM, Bote Man <bote_radio@botecomm.com> wrote:
I am an absolute newbie to FS, but from reading about dialplan regular expressions this morning I would guess that this line:
<condition field="caller_id_number" expression="^(\d+)">
is missing the required trailing "$" to end the regular expression.
It should be: <condition field="caller_id_number" expression="^(\d+)$">
no?

i already have it setup, my calls go through to the right extensions and I have done some rewitting in public.xml file, but I have having some wierdness on the handsets with call ID, when the phone rings the ID show correctly but when its picked up it shows it with the ;national... sting included.
Here is how I have done the routing and rewritte:
<extension name="105"> <condition expression="public" field="context"/> <condition field="destination_number" expression="^403XXXXXXX(.+)$"> <action application="transfer" data="105 XML default"/> </condition> </extension>
public.xml <extension name="set caller id" continue="true"> <condition field="caller_id_number" expression="^(\d+)"> <action application="set" data="caller_id_number=$1"/> <action application="set" data="effective_caller_id_number=$1"/> </condition> </extension>
Thank You, George

Why? What is your goal? This should be a simple dialplan rewrite really.
