[asterisk-users] dialplan number matching

[Vieri]

Hi,

How can I match an extension "ending with 3" (just an example but applicable to any other digit, including * or #)?

exten => _ZX.3,n,...

exten => _ZX.#,n,...

(the above does not work)

Can regular expressions be used in the standard dialplan (end with: "$")?

Thanks,

Vieri
