hello,
what is the usual method to use the cpl module when a pstn gateway needs
to know which user is responsible a call?
e.g. i have a pstn gateway pstn.example. numbers are dialed by
specifying them as user part of a sip uri => 00321234(a)pstn.example. as
the gateway is an asterisk box i'm rather flexible in choosing a method
which specifies how the name of the remote-user is transfered to the
gateway.
if a user does a forward to the pstn (e.g. in the case of no-answer) he
should also be accounted for the call - so i either need to set the
'From' header to the owner of the cpl script or i need to add another
header like 'X-account' which specifies the owner.
a solution for this seems to be to store the name of the callee in an
AVP before executing the script and to set the From field in proxy_route
after the script has started.
are there better or more-standard solutions for this problem?
bye,
