Description:The workaround is simple, but this seems like a bug.

In the scenario where a local context is called from a regular one with a SINGLE DIGIT extension but a MULTI-DIGIT pattern, it fails.
[2012-05-18 11:18:43] NOTICE[16991]: chan_local.c:899 local_call: No such extension/context 5@context-local while calling Local channel

exten => s,1,Dial(Local/5@context-local/n,60,gr)

exten => _X.,1,NoOp(${EXTEN})

If we add a single digit pattern, it works fine for both.
exten => _X.,1,NoOp(${EXTEN})
exten => _X,1,NoOp(${EXTEN})

well this is not a bug but as "." is matchin on 1 or more digits and with a X in from you need at least 2 digites to match
you must use _X! instead as "!" is matching on 0 or more digits

We had upgraded from 1.4 to 1.8. Is it possible that _X. in Local channels in 1.4 USED TO allow 1 or more digits instead of 2 or more?... Because this one little bit of code is the only thing that stopped working. And I had always presumed _X. was one or more characters... Amazed (and stupid). Thanks.
