Defining recall functions for VoIP (hook recall)
Your VoIP provider may support special performance features. To make use of
these features, your phone needs to send a specific signal (datapacket) to the SIP
server. You can assign this "signal" as an R function to a function key or a display key
on your phone.
If you press this key during a VoIP call, the signal is sent.
Requirement:
u
DTMF reminders via SIP info messages are activated, i.e., the SIP Info option on
this web page is activated
u
The R function is not used for call transfer, i.e., Use the R key to initiate call trans-
fer with the SIP Refer method = No is set for call transfer
If one of these prerequisites is not fulfilled, the fields in the Hook Flash (R-key) area
are hidden.
