Stefan,
This should be easy to do but I would start by first trying to get it to
work within your dialplan then work on the bit that triggers the call from
a file or external command.
For the case that a line declines the call... make sure that the device
does not have a call forward programmed into it. Some devices will
automatically initiate a transfer to another extension if it is on DND or
declines the call and this is outside of Asterisk's control. You would
want to disable that device feature.
I have the scenario you describe working in my dialplan with this code
snippet...
same =
n,Set(myringdevices=${IF(${DB_EXISTS(actionlist/ringdevices)}?${DB_RESULT}:SIP/101)})
same = n,Dial(${myringdevices},${myringtime},r(ring)ig)
same = n,NoOp(${DIALSTATUS})
same = n,GotoIf($["${DIALSTATUS}"="ANSWER"]?hangup)
same = n(noanswer),Goto(voicemenu-leavemessage,s,1)
I get the list of extensions to call from the asterisk db, e.g.
"SIP/101&SIP/102&SIP/201&SIP/202&SIP/203" but default to SIP/101 if the db
entry does not exist.
myringtime is set to something like 30 seconds.
Dial command options...
r(ring) indicate ringing to calling party.
i ignore forward requests received as a result of dialing (this may help
with decline)
g proceed to next diaplan step if destination hangs up.
Try something like this and use the asterisk console with debug and
verbosity so you can see what is happening.
David.
