This was just recently fixed in SVN branch 1.2, and the fix will be part
of the 1.2.8 release that will appear later this week.

In the meantime, you can work around the problem by storing the regex
string itself in a variable, then using a variable substitution in the
${REGEX()} function call, like this:

exten => ...,1,Set(MATCH="[2-9][0-9]{2}[2-9][0-9]{6}")
exten => ...,n,Set(isnum=${REGEX(${MATCH} ${EXTEN:2})})
