Hi
I was wondering if the following scenario is possible and if it is how I
would go about implementing it:
I would like to be able read from a database a list of destinations
associated with a given dialled number which are tried in order of priority
with each destination having a user definable ring duration before the next
destination is tried.
i.e.
A Call is received from the PSTN, the number the caller dialled is looked
up, it has 3 destinations attached to it, the users deskphone which is
configured to ring for 10 seconds before the call is forwarded to their
Mobile phone with a ring duration of 15 seconds, which if unanswered would
be redirected to the main switchboard IVR.
I think im looking for the equivalent of the Asterisk Dial app, where you
can specify a timeout as an argument, is this possible to do with
kamailio? All examples I have seen use a global timer value, which is
unsuitable for this requirement, as each user could define n failover
routes each with a distinct timeout before the next route is tried.
Currently I have got as far as querying the database to retrieve the data
but im a bit stumped as to how to handle the timeout variable.
Set fr_inv_timer_avp module parameter:
modparam("tm", "fr_inv_timer_avp",
"$avp(my_fr_inv_timer)")
Then put your database value into the avp. Tm module will time out after
that many milliseconds and call your failure_route, where you can try the
next destination or generate an error.
