EN
If the internal MSN in the ISDN user settings agree with the external MSN,
then the ISDN telephone can be operated without the LANCOM Business-
VoIP-Router just as if it were directly connected to the NTBA.

Further information on life-line support can be found in the user
manual for your LANCOM Business-VoIP-Router and in the LCOS
reference manual.
ECT setting
ECT (Explicit Call Transfer) is the spontaneous connection of two active calls
by the user: If you are conducting two conversations, you can transfer the two
callers so that they can then communicate with each other (’Spontaneous call
management by the user’
→
Page 29).
An ISDN telephone can transfer and interconnect the two active calls itself—
even without a PBX. The ISDN telephone connects the two calls with each
other internally and the two callers can speak with one another directly. The
disadvantage of this variant is that the two lines which would normally be
available on the ISDN telephone are both engaged. The user who connected
the two callers can no longer conduct calls and is not able to receive calls for
as long as the other two continue their call.
