18.1.4 SIP Refer Transfer
Description
If enabled through system programming, calls transferred to a SIP CO line will be transferred using the SIP
service provider’s Transfer feature instead of the PBX’s.
The following types of transfer are available:
Attended Transfer
Transfer is completed after announcing the transferred party.
From the extension user’s perspective, this is the same as Call
Transfer with Announcement (
®
Blind Transfer
Transfer is completed immediately after dialing the transfer
destination’s number.
This is similar to Call Transfer without Announcement (
®
4.1.10 Call Transfer), except that the transferrer does not hear
even a ringback tone; the transferred call is connected directly
to the destination.
Conditions
[General]
•
The availability of this feature depends on the SIP service provider.

[Blind Transfer]
•
ISDN extensions and SIP extensions cannot use this feature.
•
This feature cannot be used when calling through DISA (
®
5.1.10 DISA (Direct Inward System Access)).
