The first paragraph under "SIP CHANGES" in CHANGES reads:
" * Added support for SUBSCRIBE/NOTIFY with dialog-info based call pickups.
   Snom phones use this for call pickup of extensions that the phone is
   subscribed to.
"

I bet it's this code that messes with you. I am not aware of the details of the implementation, so I can't say if there's a way to turn it off.
