there is no special handling for the diversion header in v2.6.

adding a new field in the CDR means changing at very least the:
- kamailio proxy config
- mediator
- cdr exporter
they come with a source code so everything is possible.

is User1 on the sipwise CE or not? If it is subscriber on SPCE and it
makes a call forward, you know this from the call_type field:
http://www.sipwise.com/doc/2.7/spce/ar01s09.html#_file_body_format

If it is in PSTN and the call comes in to SPCE with Diversion header,
you could try playing with v2.7. There you have a possibility to fetch
the Diversion number from inbound request and send in in some header
outbound using the peer (and domain) preferences. Just set inbound_uprn
to "Received Diversion". You still need to care about storing uprn in
the CDR records, AFAIK this is not on our roadmap yet.
