Set up an incoming SIP connection
There are two ways to answer an incoming telephone connection (SIP):
1.
Whitelist for recurring known phone numbers:
For recurring incoming SIP calls from known telephone numbers, it is recommended to assign these
numbers to certain keys. The V615 Industrial call station generally accepts all calls from the registered
SIP server and plays the caller in the internal loudspeaker. If the call is not accepted by pressing the
corresponding key on the V615, the "Missed call" is displayed by the corresponding key flashing. This
status is reset after 60 seconds.
For recurring incoming SIP calls from known telephone numbers, it is recommended to assign these
numbers to certain keys. This automatically assigns these numbers to the whitelist. All unassigned
phone numbers receive a busy signal if the "
Callback
" function is not activated. Answer an incoming
call by pressing and holding the corresponding key (signaling by flashing).
If the call is not accepted, the "Missed call" is indicated by the corresponding key flashing quickly. This
Status is reset after 60 seconds.
2.
Callback Function
If it is desired that phone numbers are accepted that are not on the whitelist, you can use the
"
Callback
" function. As soon as you have assigned this function to an unassigned key, the V615
Industrial Callstation accepts all incoming calls. You can then use the predefined key to answer the last
incoming unknown call. If you miss the call, the station saves the last number on the Unknown
destination key so that you can call it back.
The "
Callback
" field is located under the last key of the "
Key
Configuration
" segment. The key number
you enter in this field must be unconfigured and is then used to store the last unknown number. The
call function of the corresponding key is automatically switched to "
Telephone Call
".
