François,

The answer to your question (dated Apr 13 2013) is yes:

I'm hoping that this matches up with your earlier post so that others can find it (I'm new to the Freeswitch mailing list, so I couldn't just reply to the message.)

With the help of Allamamond here on the list, I was able to do the following:

Unique-id should most likely be . . . um - unique (although it worked fine for me when it wasn't)

And I tried a virtual id for the from and login. For example"kpmtest@192.168.1.99" worked fine. On the phone (yealink) I just used "6001" or "kpmtest" in the BLF without the trailing domain.

Answer-State could also be "confirmed" or "terminated"

Finally, this was working with 1.2 Freeswitch.

HTH
