STD SIP Transfer-Unattended
Description
With SV9100 software, any standard SIP terminal can perform an Unattended (Blind/Unsupervised)
transfer. Refer to transfer-Unattended of draft-ietf-sipping-service-examples-15.txt.
Conditions
Program15-05-50 (Peer to Peer Mode) must be disabled for the Unattended Transfer to be
performed.
A SIP terminal must receive the re-Invite message of Session Timer in a state of
Unattended transfer.
When the transfer destination terminal is busy, unanswered or the extension number in the
Refer-To header is wrong or out of service, the call is sent back to the original terminal.
If the standard SIP phone is placed on hold/park from another extension, this call cannot be
transferred until the station that placed the call on hold/park retrieves the call. An
unattended transfer can only be completed while both parties are in a talking state.
The SV9100 supports both Attended and Unattended transfers.
An unattended transfer can only be performed to the following locations:
Extension Number
Department Group Pilot Number
Group Pilot Number
Operator Access
Trunk/Alternate trunk access code
F-Route Access
Network Access
Quick transfer to Voice Mail is not supported when using Unattended Transfer.
