T46S: Easy way to do either attended or blind using DSS BLF keys?

[CEPM Nate]

The main reason I want to do EITHER is so the ORIGINAL caller id is visible when the call is forwarded.
According to this thread: http://forum.yealink.com/forum/showthread.php?tid=41102
I should be able to add the following

Quote:account.x.refresh_remote_id.enable = 1
features.save_init_num_to_history.enable = 1

into the config file, but adding them via the web GUI (Config -> Export -> modify_file -> Import -> Export_to_check_them), shows that new lines don't actually get added to the config file! (yes, I put in account.1...., not X)

I've even tried to get an auto-provisioning server set up just for this case, and I can see in the IIS logs that the phone requests MAC.cfg file and gets a status 200 (http code means success), but when I check via Config -> Export, the new lines are DEFINITELY not there. Seriously, why on earth does the phone CFG import not actually import the file? Or better yet, why doesn't it come with a straight-forward way to do attended AND blind transfers using the DSS keys? I like the hardware, but this inability to edit the CFG file and upload it is driving me nuts. Anyone else hit this?
