[asterisk-users] Grandstream blind transfer issue

[Max Alex]

Hi
I have used the transfer operation this way.
When i got a call on grandstream phone, i will receive it
and press transfer button and enter transfer number and press send button.
My call is disconnected but no call transfer from asterisk.
Please advice me!!
Thanks,
Max Alex
