different bearer capabilities are used to signal
the type of data (Voice, Data, H320, H.324M),
which is used by telephony switches and other
equipment to determine how to handle data
or calls (compressing voice data neglect etc).
The outgoing bearer capability sets the ISDN
bearer capability for the outgoing telephone
(voice only) and video telephone calls.

H.324M: This ITU standardized capability

•

is selected for outgoing calls by default.

UDI: In some situations the switch does

•

not accept calls which use the correct
H.324M capability. This setting makes it
possible to use the 3G Gateway in these
situations via selecting UDI.

pane.

You cannot configure
ISDN BRI lines for
special functions like

dial out only! The Gateway
will automatically select a
free BRI line for H.323 to
3G calls and possibly block
a DiD or an IVR menu when
the BRI lines have different
numbers. Consequently, we
strongly recommend that
all ISDN BRI lines have the
same number range!
Contact your ISDN or
telecom supplier about
numbering plans of ISDN
lines.

All incoming calls are accepted
independent of their bearer

accepted as well.
