Asterisk dialplan designed for use with OpenBTS; This dialplan is specially designed for use with OpenBTS. ; It can also be used as an Asterisk based solution without using mobile phones. ; It provides full hotdesking for all phones registered and configured with sip entry in ; /etc/asterisk/sip.conf ; ; SIP entries in /etc/asterisk/sip.conf ; SIP entries in sip.conf has to look like this: ; ; [IMSI204123170034543] ; callerid=IMSI204123170034543 <IMSI204123170034543> ; canreinvite=no ; type=friend ; allow=gsm ; context=sip-internal ; host=dynamic ; ; Be aware of the fact that with SIP entries as above smqueue will not work properly. ; ; Automatic configuration of discovered IMSI numbers should be easy ; Because no dialplan info has to be added, automatic configuration of a SIP entry after ; discovering should not be that hard. The use of a file for every SIP entry included ; in SIP.conf is the way to go for this. ; ;*Simple, safe and flexible dialplan* ; This dialplan provides flexibility and seperates the SIP registration based on IMSI ; number and the actual phone numbers used to call. ; ; The basic idea behind this dial plan is to keep it as simple, safe and flexible ; as possible. It can be used as a ready to go solution but it might be ; a good idea to make some adjustments based on particular needs. ; ;*Number range 1001 - 1012 preconfigured* ; The number 1001 to 1012 are preconfigured. Expanding the number range is ; just a matter of copy and past of all the 1001 to 1012 parts in the dialplan and make some ; adjustments on the numbers. The dialplan should suite every OpenBTS deployment. ; ;*Logging in* ; When a mobile phone is registered to OpenBTS and Asterisk it needs ; to be logged in for a phone number. This is done by dialing 0<phone number>. ; Dialing 01001 makes the phone reachable at number 1001 and set the callerid ; to 1001. By default the pincode is 1234 but this can easily be changed. ; One phone can log in an unlimited number of phonenumbers. The limitation is ; the the range of numbers available within the dialplan. ; ;*Logging off* ; Dial 1<phonenumber> to log out of a phone umber. The result of dialing 11001 is that ; the phone is no longer reachable at number 1001 ; ;*Automatic log off* ; A phone number will be logged off if a call is made to that number and the status is ; UNAVAILABLE. ; ;*Logging in is needed to make useful calls* ; A phone registered to the OpenBTS and Asterisk but not logged to a phonenumber ; can't make any usefull phonecalls. Any dialed number is routed to an Asterisk ; music on hold extensions or the monkeys screaming. This can be changed to personal ; needs like a voiceprompt that let the caller know that a login to a number is needed. ; This provides security to this solution. You need to have the proper credentials to make ; phonecalls. ; ;*Using a trunk* ; The dialplan is ready for use with a trunk so outbound calls can be made if the connection ; is actually there. In the dialplan all numbers of 10 positions are routed to the trunk. ; In the Netherlands this enables making national phonecalls. A phone needs to be logged into ; a phone number before an outbound call can be made. The numbermatching ca be changed to your needs. ; OPENBTS_TRUNK is the global variable to store the trunk. ; ;*Special numbers* ; Some special numbers, handy when testing, have been added to the dialplan: ; 01234 -> releases all logged in numbers. be aware that if you call this number and enter ; the password (default 1234) all phones are without an actual number. ; 02345 -> shows all phonenumbers and, if available, the IMSI number related to the phonenumber ; in the Asterisk Cli. ; 03456 -> shows the device state of the SIP registered IMSI numbers in the Asterisk Cli. ; This doesn't work at the moment while it should :-( ; 02000 -> a music on hold extension. ; ; Absolute timeout ; Set(Timeout(absolute)=XX) is used now and then so calls without the proper credentials ; end within a certain time. XX is the number of seconds before the connection will be ended. ; ; 4 different scenarios for a call ; Different things can happen when dialing a number, depending on the status of the phone used and the ; status of the number called. Info about the actual status can be viewed from the Asterisk Cli with verbose ; set to 5 (set verbose 5) ; ; scenario 1 ; The phone used to dial a number hasn't been logged in. It is not possible ; to make any call without first logging in with a proper combination of number and password/pincode ; ; scenario 2 ; The phone has been logged in properly but the number dialed isn't logged in ; ; scenario 3 ; The phone has been logged in properly, the number dialed is logged in but the phone is switch off ; or out of range. When this happens the dialed number is logged off. Because OpenBTS does return a SIP code ; that Asterisk doesn't translate in a CHANUNAVAIL but in a NOANSWER dialstatus the handling of this status doesn't ; work properly. This isn't a real problem because the phone isn'r reachable anyway. The result is that the login ; stays in place despite the fact that the phone is turned off or out of reach. ; ; scenario 4 ; The phone has been logged in properly and the number dialed has been logged in properly. the dialed phone will ; ring and probably be picked up ;-) ; ; When a trunk is configured the phone used to dial an outbound number has to be properly logged into ; The global variable OPENBTS_TRUNK is used to store the actual trunk. ; ;*How to install this dialplan?* ; Just do a select all of this wiki text and do a paste in an empty file. Save this file as /etc/asterisk/extensions.conf ; add some sip entries like the example at the beginning of this text to /etc/asteisk/sip.conf and do a reload. ; Now you are ready to go ;-) ; ; Hope it is useful and you will have lots of fun! ; ;Erik ; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ; auteur : Erik de Wild ; company : Tripple-o : Your Asterisk migration partner ; e-mail : info at tripple-o.nl ; phone : 0031621830837 ; ; Rights : Tripple-o owns the rights to this dialplan ; Country : the Netherlands ; Time Zone : GMT +1 ; ; version : 1.0 ; date : 24 december 2009 ; License : This dialplan is GPL3 licensed with the condition that ; this header (from top to [global]) is kept in place, credits are addressed and you don't charge ; money for the dialplan as it is.
