If you are setting the userfield in the 'h' extension, then this is
what I would expect. CDRs are finalized when the path of communication
between channels is finished; altering the data after that point
updates the next CDR for that channel. It isn't retroactive.

The 'h' extension is special in that 'endbeforehexten' explicitly
ignores updates in 'h' extension. If you disable 'endbeforehexten',
then you will get a CDR for the channel while it updates the hangup
logic - but again, modifications occur on that CDR, not on previous
ones.

If you want the CDR for the channel prior to the 'h' extension to have
a userfield entry, you have to apply it before the channel hangs up.
