[asterisk-users] How to handle multiple lines call

[Mc GRATH Ricardo]

Hi Thyda

When you set "exten => _.,1,Dial(SIP/${EXTEN})" Asterisk assume "_.", an match  everything on your dialplan including special extensions as "i", "h", etc.,  these will cause problems onto your system.
If you need to match one or more digits you can use _x and _x.
_x it mean only one pattern digit form 0 to 9
_x. any pattern digit from 0 to 9 and dot it mean remnant digits could be 2 or 3, 4 ... etc., so what ever you dial  on sip it will be valid.
