The availability of this feature depends on the SIP service provider.

PBX for further handling even if the transfer fails.
[Blind Transfer]
•
ISDN extensions and SIP extensions cannot use this feature.
•
This feature cannot be used when calling through DISA (® 2.16.1 Direct Inward System Access (DISA)).

Feature Manual
Transfer is completed after announcing the transferred party.
From the extension user's perspective, this is the same as Call
Transfer with Announcement (® 2.12.1 Call Transfer).
Transfer is completed immediately after dialling the transfer
destination's number.
This is similar to Call Transfer without Announcement (®
2.12.1 Call Transfer), except that the transferrer does not hear
even a ringback tone; the transferred call is connected directly
to the destination.
