8.6 VoIP
This section only applies if the SIP protocol is used in the system.
8.6.1 Add instance id to the user registration with the IP-PBX
This might simplify administration with some IP-PBXs.
1 Select VoIP > SIP.
2 To enable, select the "Add instance id to the user registration with the IP-PBX"
check box.
3 Click "OK".
8.6.2 Session Timer (initial value)
If set, a keep-alive mechanism will be used to detect if a call is still valid as defined by rfc
4028. This is normally handled by the IP-PBX and then not necessary to be defined here.
1 Select VoIP > SIP.
2 To enable, enter a time (sec.) in the "(Session Timer initial value)" field.
3 Click "OK".
