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>

</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

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

I appreciate you help.

Best regards,
