Blind Transfer During Connection

Description

The regular Call Transfer is capable of doing transfer only after a successful inquiry to another station during connection.
This means if no answer during inquiry it is not possible to transfer the call to a private ringing station or a ringing group.

Blind transfer is based on the Inquiry Call feature.
Configuring Inquiry with parameter 1 = 1 will activate transfer directly to the feature directory number dialed during Inquiry.

Change "ID" to "1" to turn digit "2" during a call into a Blind Transfer

This extends the transfer feature to also give the possibility to do transfer to:

• Stations in private
• Ringing groups
• SIP phones
• Group call
• ++

In combination with automatic search a switchboard operation can be made.
The search string number counter and station is reset when preforming a blind transfer.
Example:

• A is a switchboard defined as ringing group 1.
• B and C are users with automatic search on private ringing /busy programmed as ringing group 1.
• D is someone calling to the switchboard, could be SIP or AlphaCom station.

1. D calls A
2. A does a blind transfer to B, B is private ringing
3. After private ringing timeout D is activating ringing group 1 call back to A, from B's first search string
4. A does a blind transfer to C, C is busy
5. D is activating ringing group 1 call back to A, from C's first search string

etc. etc.

Known limitations

• A (AlphaCom) calls B (SIP) and A try to transfer B to a ringing group. This is currently not supported. ( A (SIP) calls B (AlphaCom) and B transfer to Ringing group is working)
