[asterisk-users] pattern matching "+"

[sean darcy]

 From my provider I get extensions of:

+1<10digit number>
1<10 digit number>
<10 digit number>

seemingly randomly.

What I'd like to do is

exten=_!1234567890,1,Answer()

which would match anything ending in 1234567890.

But that doesn't work since ! can only be used at the end of a pattern.

I tried

[+\ ][1\ ]1234567890

which didn't work, probably because "\ " means  space, not nothing.

Any suggestions?
