> The way that asterisk handles the CDR for blind transfers has changed between version 1.8.7.0 and 1.8.18.0. The call path is: inbound call from SIP provider -> asterisk server -> SIP peer -> transfer to another SIP Peer. The transfer is done by using the dedicated keys on the hardware and not the features.conf method.
> In version 1.8.7.0 this would produce 2 entries in the CDR, 1 showing the time the inbound call started and which context it was handles by, the second showing the the context the peer belongs to and looking like an extension to extension call.
> We tried upgrading to 1.8.18.0 and did some regression testing and found that the CDR now only produces a single entry with the details all pertaining to the second leg of the call (bar the duration which is for the full life of the call). It has no reference to the inbound context that initially handled the call.
> This is a pretty big change to be inside a single branch and I'm guessing it wasn't intentional.
> Also, all our servers are installed using Puppet so the configuration on them all is the same and we use RealTime Architecture from a single database.
> Here is an example (with sanitised data):

> In the newer version there is only one entry which has the combined call
> time in it but the dcontext corresponds with the second leg of the call
> which means we can't see what number was dialled.
