Trunk to Trunk Transfer
n Description
Trunk to trunk transfer refers to the connection of any two trunk ports together.
Hold and Transfer.
An extension user places one trunk call on hold and then either makes an outgoing call, answers an
incoming call or retrieves a call from hold and transfers the two trunk calls together.
Withdraw from Conference.
An extension user sets up a conference call with two (or more) trunk calls and then withdraws from the
conference, leaving the trunk callers connected.
Extension User sets Call Forward Off Premise.
An incoming trunk call is routed to an extension with call forward off premise. The user can set call
forward off premise by setting call forward to an Abbreviated Dial bin or by Service Code
713+6+Trunk Access Code+off premise number.
A Trunk is routed directly Off Premise.
The Aspire is configured to route the incoming DDI trunk directly to an off premise number. This is
set in Program 22-11-02 by entering the trunk access code followed by the off premise extension
number as the target for the DDI number e.g. 901509643111.
Conditions
Two outgoing analogue trunks can not be connected together, this is because a disconnect clear signal
is not generated by the PSTN for calls originated by the PBX.
The following tables show the settings required to allow the various trunk to trunk options.
