SPA50x has both blind and attended transfer buttons and BLF can be configured. Set server type on the Attendant Console tab to the RFC one, and set up the line keys. The line keys are multipurpose and programmable on these phones and can either be used to select sip accounts, as quick dial/BLF/call-pickup, or to launch custom XML applications.

For the line key button settings you do:

func=sd+blf;sub=<user>@$PROXY

You can add in call pickup, too:

func=sd+blf+cp;sub=<user>@$PROXY

which when the monitored extension is ringing, pressing the button will dial **<user> (the user prepended with 2 asterisks)

Do most of these phones offer a 'transfer' button?

Do the Siemens/Gigaset Desk phones offer BLF that anyone has used?

What about the Cisco SPA50x ?

BLF is THE feature I need for the 2 phones.  ( I haven't seen BLF on any of the softphones I played
with.)

I also have a page for soft-phones started- heavily Linux centered.
