Call Jump
Call Jump allows users to seamlessly jump the current call to a predefined alternate or wireless
number by entering the designated hotkey.
The main difference between call jump and call transfer is that when you transfer a call via call
jump, the current call will stay connected instead of being placed on hold.
The following table lists the default call jump hotkeys configured by Metaswitch. Internet
Telephony Service Provider can modify the hotkeys, depending on your actual needs.
Dial *95 to jump to your alternate number.
Dial *96 to jump to your wireless number.
Dial *90 to disable call jump feature temporarily for avoiding hotkey
conflict issues.
Note
Scenarios A:
The system administrator has configured the alternate number (B) that phone A may want to
transfer calls to in CommPortal.
The hotkey is transmitted through DTMF. To use call jump feature, you need to set the value of
the DTMF Type to AUTO or SIP INFO and the value of the DTMF Info Type to DTMF-Relay. For
more information on how to configure the method of transmitting DTMF digits, refer to DTMF
