18.1.5 SIP Server Failover

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
Blind Transfer
Conditions
[General]
The availability of this feature depends on the SIP service provider.
Since the SIP service provider takes control of the transfer, the transferred call cannot be returned to the
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 (® 5.1.10 DISA (Direct Inward System Access)).

18.1.5 SIP Server Failover
Description
When communicating with a SIP server (e.g., when the V-SIPGW card is in INS status, when sending periodic
REGISTER requests), if the SIP server does not reply after sending the REGISTER/INVITE request, the
REGISTER/INVITE request is sent again using one of the following methods.
If a failover SIP server is registered, the REGISTER/INVITE request is sent to that server.

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 (® 4.1.10 Call 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.
