Hi, 
Have noticed the following entry in the system log, wondering what it is: 
NOTICE[6828] res_features.c: Don't know what to do about control frame: -1. 
It seems to be associated with transfer from the  SPA941, but not the ATAs. 
The only difference I am aware of in transfer is that the SPA 941 user  ## to transfer whereas the ATA users 'R' (tbr).  In both cases transfer is successful (although the SPA941 method noticeably takes quite a few seconds before the target ext rings, while the ATA method is instant). 
Regards 
Ron
