[Freeswitch-users] Dialplan expression matching

29 Sep 2016

      Hi,

I've mentioned that pattern matching in my dialplan works incorrectly but I
can't figure out the main reason.

For example I have the following dialplan:
<context name="internal">
    <extension name="echo_test">
        <condition field="destination_number" expression="^(echo|9999)$">
             Some action
        </condition>
    </extension>
    <extension name="is_internal_call">
        <condition field="destination_number" expression=".*"/>
        <condition field="${sip_h_X-Exten-Type}" expression="internal">
              Some action
         </condition>
    </extension>
    <extension name="ua_local">
        <condition field="destination_number" experession="^[2-5][0-9]{6}$">
            Some action
         </condition
    </extension>
    <extension name="ua_mobile">
        <condition field="destination_number" experession="^0[0-9]{9}$">
            <action application="bridge"
data="sofia/gateway/golden/${destination_number}"/>
        </condition>
    </extension>
</context>

1. Call to "echo" - OK (echo_test)
2. Call to some extension with custom header X-Exten-Type - OK
(is_internal_call)
3. Call to 5930000 - OK (ua_local)
4. Call to 0930000000 - FAILED to match ua_mobile extension.

The last call matches ua_local. But why?

The result of regex dp_tool
freeswitch@vlakas> regex 5930000|^[2-5][0-9]{6}$
true
freeswitch@vlakas> regex 0930000000|^[2-5][0-9]{6}$
false

So, everything is correct. I can't understand why almost everyting goes to
ua_local extension.

I appreciate you help.
