    <condition field="caller_id_number" expression="^\+?(12243336164|12025551212)$">

(The corresponding action routes the call directly to my extension, but that's not important.)

The reason I have "\+?" is I didn't know if the plus sign was included in the caller-ID.  I have since learned that it is, so I can remove the "?", but I still want to know what I did wrong.
