[OpenSIPS-Users] Question about cache_store and lifetime of variables

[Saint Michael]

I noticed that the variable
$avp(lineid)
set in the section of the code handling the original INVITE, is null when I
need to close the call.
Is there a way to store a variable that will be available throughout the
call, everywhere?
I am trying:
cache_store("local","lineid_$ci","$avp(lineid)",0);
but I need this value to disappear when this call is closed. I cannot set
an expiration because the call may last for 2 hours or 2 seconds.

many thanks for your help and guidance

Philip
