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@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, /gst
