Perhaps your IOS? Worked fine for me:
dial-peer voice 222 voip
destination-pattern 428(8888|9999)
session target ipv4:1.1.1.1
I'm just running 12.2(2)T1 on it, so it's not even the most current....
try putting a + before the 4 and see what happens. The E.164 stuff was
supposed to be deprecated, but who knows. :)

Hi Scott,
I remember I tried it too but no way:
Rack1R5(config-dial-peer)#destination-pattern 428(8888|9999)
Incorrect format for E.164 Number
regular expression must be of the form
^[][^0-9,ABCD#*.?+%()-]*T?(\$)?$
:((

That would be correct, which would mean you'd match the peer as soon sa your
dialed 4288 or 4289. :)
You may also be able to do interval configuration. Intervals are set up
with the {} immediately following the expression in question.
So an answer to your lab would be:
428[89]{4}
Which will match 428 plus EXACTLY 4 values derived from either 8 or 9. Note
that you could also match 4288989 and other variables like that. So that's
not likely either.
That brings us to the class theory with (). The parentheses can be used to
denote multiple characters together as a string to look at. They are
treated like a single character is at that point.
So the "real" answer to you scenario permitting ONLY those two options
should be:
428(8888|9999)
The "|" represents OR and the other two sets of digits represent one thing
solved in the equation. So if you use this as your destination pattern, and
check it out by "show dialplan number 4288989" you shouldn't get a match.
Hope that helps!

Thanks for the explanation. I thought I had to put a comma to separate
characters :(
In a scenario the requirement was to have a dial-peer that match both
strings: 4288888 and 4289999. I did find no way to do it even with the
doc-cd so I looked at the solutions and surprise !?!?!? It was:
Destination-pattern 428[8888,9999] !! Previously I thought it was not
possible ...
So this means, 8 or 8 or 8 or 8 or 9 or 9 or 9 or 9 ?
Thanks,
--Richard

Based on all the docs, and examples, the [] are used to contain a single
digit. An implicit "or" exists between ANY character listed. (Called a
'character class' by the way)
With the ranges you had:
[11-12] means match '1' OR the range '1-1' OR '2' as the single character
[11-102] means match '1' OR the range '1-1' OR '0' OR '2' as the single
character [98-102] means match '9' OR the range '8-1' (which is invalid) OR
'0' OR '2' as the single character
Hope that helps with things! But it really is just a single character
match!!

Funny, the doc says "Note <<...>> Only single-digit ranges are supported.
For example, [98-102] is invalid" here

But actually it works depending on the numbers entered !!?!?!? Anyone can
clarify this ? Please see below:
