Blind Transfer During Connection

Description

The original AlphaCom is only capable of doing transfer after an 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.

Direct transfer is based on the Inquiry during connection feature (55). Configuring Inquiry with parameter 1 = 1 will activate transfer directly to the feature directory number dialed during Inquiry. This extend the transfer feature to also give the possibility to do transfer to:

• Stations in private.
• Ringing groups
• Group call
• ++

In combination with automatic search, the search string number counter and station is reset when preforming a direct transfer. <br\> 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, <br\> 2. A does a direct transfer to B, B is private ringing <br\> 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 direct transfer to C, C is busy <br\> 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)
