EN
Under LANconfig, start the setup wizard for configuring the VoIP Call
Manager. Enable the options 'SIP phone system', 'ISDN phone system'
and 'ISDN users'.
Configure the device as described in the preceding examples:
Unique local VoIP domains
One line to a SIP provider
Enable the external ISDN outside line and the internal ISDN bus in order
to use the VoIP functionality. Enter all external MSNs for the ISDN outside
line in the ISDN mapping table with their assignment to the internal num-
bers in the VoIP range.
Enter all connected ISDN terminal devices as ISDN users with the follow-
ing values:
Telephone number / SIP name: This number will be assigned to the
ISDN terminal device as an "internal number". The telephone struc-
ture will remain clear if you use the same internal number for a termi-
nal device here as it uses in its own ISDN environment.
MSN/DDI: Enter the external MSNs for the ISDN outside line here; this
will also be assigned to the terminal device by the ISDN PBX.
Enable spontaneous outside line access for ISDN and SIP users in order to
keep the subscribers' telephone behavior as consistent as possible.
