blind transfer problem with snom

[lirees]

Hello all
I can not make a blind transfer with my 3CX v9 sp3 and snom 320 firmware 7.3.30

- answer the call
- press the blf key
- hangs up

the exstension ring properly and the display shows the caller's number, but my phone is not free, the display of my phone will continue to see caller's number as if still connected, only when the extension which i transferred the call answers my phone becomes free.

If i transfer the call by digit the exstension number without using the blf key everything works fine

I update the firmware to the last release but nothing changes

I forgot ... the same problem with the 3cx v8

I just found out that I have the exact same problem with my Snom phones (see my signature for details).

Scenario:
- I'm online 1 with person A
- I transfer the call to person B using "transfer + BLF"
- Person C is trying to call me on Line 2 (which is blinking on my phone)
- I can't pickup line 2 until person B answers the transfered call

I was able to work around this problem by pressing X (cancel) right after the transfer is done.

When I transfer a call using the extension number instead of the BLF, this problem does not occur.

I will also post this on Snom's forum because I think it's more a phone issue than a 3CX issue.

Thank you
