I read 'Elastix whithout tears' and tried to configure 'Parking lot'. Whatever I does in that page (click checkbox,change time,change parking lot extension etc) - nothing happens indeed! I see changes in parking_additional.inc but i think that asterisk core does not read this file. I transfer a call to 70 but i am said that it's "not a valid extension". I know that pure asterisk have parking lot extension = 700. I tried and it worked! But doing anything by web gui does not affect. Is it a bug?
