Dear Asterisk-Users, does anyone know how to prevent non-free calls to Broadvoice Unlimited World ? This first thing I did is I accept only that coutry prefixes (in extensions.conf) that are in the Unlimited World dialplan. I was also able to filter out german cell phones (cause they begin with 1 and no landline is beginning with 1). US is also no problem as cell phone calls are unlimited too. But what about the other 19 countries how do I filter out cell phone calls ? Are calls to canadian mobile phones also unlimited ? Does anyone know ? Is the anywhere a List of all cellphone prefixes for that 19 countries ? I did not found something with google. That is what I found in the broadvoice wiki : -------- exten=_01130.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01131.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01132.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01133.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01134.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011351.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011352.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011353.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011378.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01139.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01141.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011420.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01143.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01144.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01145.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01146.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01147.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01148.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01149N.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01154.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01155.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01156.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01160.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01161.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01164.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01165.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01181.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01182.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011852.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_01186.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011886.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011972.,1,dial(SIP/${EXTEN}@sip.broadvoice.com,30) exten=_011.,2,congestion() ; No answer, nothing exten=_011.,102,busy() ; Busy -------- Thank you very much Sebastian
