Hi. i am running asterisk 11 and i would like to have features access codes in my system such as call waiting(all types) (enable/disable), call forward
(enable/disable) and DND. my dialplan is pretty simple and it is the following

[DefaultPlan]exten =>
_XXXXXXXXXX,1,Dial(SIP/VoipGate/${EXTEN},120,Tt)exten =>
exten => _4XX,2,Answer()exten =>
_4XX,3,VoiceMail(${EXTEN}@Office,su)exten => _4XX,4,HangUp()exten =>
_4XX,102,Answer()exten => _4XX,103,VoiceMail(${EXTEN}@Office,sb)exten
=> _4XX,104,HangUp()

i would like to enable/disable call waiting by typing eg. *70/*71
DND for the extension *72 enable, *73 to disable.

Regarding call waiting, at the moment it is disabled (default value). Now if an extension is busy, a busy message is send back to the caller. I would like have the following behavior:
-in the event were the extension is busy, then send a message indication to the extension and the caller to hear from the SIP provider the default early media for call waiting due to busy. Then after some period of time eg
30 secs send busy.
-in the event where the extension is busy, send the early media to the caller and waiting indication to the extension. If the extension decides to get the call then get the 2nd call and send the 1st to hear moh.

My phones are mainly softphones (zoiper), a few IP phones and 2 SPA3000 for analog devices.

could someone help me please with this task, please?

  • Define your *72 and *73 extensions in your internal context, Have them set a value in the ASTDB that you then check when dialing your handsets.

    The same can be done for call forwarding, store a number in the ASTDB and check if it’s present, if it is forward the call to that number.

  • There’s some example code in the Dial-Users context of the basic-pbx samples that might be of use in implementing it.

    They are checking a DEVICE_STATE to see if a phone is BUSY, You could change it to be a database call or implement custom device states and check those.

    wrapping your test case in an ExecIF statement that uses the DB_EXISTS
    function to see if the database field you are checking is valid so you don’t get errors about non existent entries.

  • at the moment i have in each extension in sip.conf the call-limit=2. Everytime someone calls that extension and that extension is busy, there is not any notification:
    – to the extension that there is a second call
    -to the calling party that this extension is on call. So the calling can either wait or hang up.

    How can i make that happen, please?
