Hi I have a PBX on a site behind a PRI line. Our telco company has issued us with 300numbers for the PRI. The range i.e. is area code 012 area 555 and mumber 1000 so its 0125551000 - 0125551300 I chose to setup my extensions as the last four digits i.e. 1000, 1045 etc. I dont want all the extensions to be able to recieve calls but for some weird reason even when an particular extension does not have a DDI programmed and the number sequence is dialed (0125551010), the PBX associates the number and allows a call through to the extension. How can i disable this I did load a custom contex for freepbx to elimintate calls to be made externally but I need to know how to stop an external incoming call to an extension. Some extensions are only allowed to dial internaly. Any ideas?
