Conversation recording with 4645

[OXO-Man]

Dear all,
I have a problem with an OXE R8.0.1 and Conversation Recording in my 4645:
I want to record a conversation and download this recording via IMAP4 on my PC.

It works fine with one problem:
In the email with the wav-file attached the From- and To-fields are the same. I want to back up these emails with the conversation recording. But I can´t see which costumer has called me cause the From and To-fields are always my email-adress.

If I get my voicemail-messages by email the From-field is the external number who has left this message.

Is there any chance to see the incoming number concerning the voice recording too?

Thank you for your answers..!!!
Best regards
OXO-Man
