Users cannot transfer calls to a destination that they cannot normally dial. This applies to manual transfers and also to automatic transfers (forwarding). In addition to call barring applied through short codes, the following system settings may restrict a users ability to transfer calls.
User Specific Controls
Setting
Description
Outgoing Call Bar
Default = Off (User | Telephony | Supervisor Settings)
When enabled, this setting stops a user from making any external calls. It therefore stops them making any external transfers or forwards.
Inhibit Off-Switch Forward/Transfer
Default = Off (User | Telephony | Supervisor Settings).
When enabled, this setting stops the specific user from transferring or forwarding calls externally. This does not stop another user transferring the restricted users calls off-switch on their behalf.
User attempts to set an external forward destination using a short code hear error tone.
User attempts to set an external forward destination using a programmable button on their phone do not allow the number to be saved.
Line Specific Control
Setting
Description
Analog Trunk to Trunk Connection
Default = Off (Line | Analog Line | Analog Options)
When not enabled, users cannot transfer or forward calls on one analog trunk back off-switch using another analog trunk.
System Wide Controls
Setting
Description
Inhibit Off-Switch Forward/Transfer
Default = On(System | Telephony)
When enabled, this setting stops any user from transferring or forwarding calls externally.
User attempts to set an external forward destination using a short code hear error tone.
User attempts to set an external forward destination using a programmable button on their phone do not allow the number to be saved.
Restrict Network Interconnect
Default = Off (System | Telephony).
When this option is enabled, each trunk is provided with a Network Type option that can be configured as either Public or Private. The system will not allow calls on a Public trunk to be connected to a Private trunk and vice versa, returning busy indication instead.
Conference Control
Users can use conference controls to effectively transfer calls. This includes transferring an external call to another external number. The use of conferencing to effect off-switch transfers can be restricted using the Inhibit External Only Impromptu Conference setting (System | Telephony).
