numeric identifier "001234" on the Cisco TelePresence MCU with the name
"my_mcu".
Example: in an IP to ISDN dial plan rule, for calls matching a condition (D*)P(D*),
setting an action to call $1!$2 will match any numbers which have a '#' in, using
the number before the '#' for the phone number and the number after the '#' as
the TCS-4 extension. (For more information about using TCS-4 see
Example dial
plan rules
)
o
Call these numbers
: this option only becomes available if you select
Video using H.221
aggregation (legacy)
as the call type (for IP to ISDN calls) in the
Additional parameters
section. Only use
Video using H.221 aggregation (legacy)
if you are supporting legacy
ISDN endpoints that need this feature. You must ensure you enter the correct number of
telephone numbers. For example, if you select 3 x 64kbps as the call bandwidth, you
must enter three telephone numbers here. Note that you can use the same scheme of
substitutions as described for
Call this number
.
6. Complete the
Additional parameters
, if required:
o
Call type
: Specify the type of outgoing call:
Telephone
: if the call is a voice-only telephone call.
Video using BONDING (default)
: a "typical" video call.
Video using H.221 aggregation (legacy)
: only select this if you need to support
legacy ISDN endpoints that require n x 64kbps or n x 56kbps channels. This
option is only available for IP to ISDN calls
o
Restrict (56k)
:
(this is only for IP to ISDN dial plan rules)
when selected, for calls
matching this dial plan rule the ISDN gateway will make the outgoing ISDN call in
restricted 56k mode. Do not select this option unless your network requires it. Note that
for a call matching a rule that uses 56k mode, if the endpoint only supports 64k, the ISDN
gateway will drop the call rather than use 64k.
o
Maximum call bandwidth
: optionally, select a maximum bandwidth for the ISDN part of
the call, which will otherwise be set to the default value. To view or edit the default value,
go to
Settings > ISDN
. The maximum bandwidth settings on the
Settings > ISDN
page
are global settings. Therefore, if you choose a greater setting in the dial plan than you
have as a global setting, the global setting will be used as the maximum value. For
example, if in the dial plan you choose to set
320kbps (5 x B channels)
as the maximum
bandwidth and the global setting for maximum bandwidth for outgoing ISDN calls is
256kbps (4 x B channels)
, the maximum bandwidth available to the call will never be
more than 256kbps.
Note that if you have selected
Telephone
as the call type, this option is unavailable and
the bandwidth set automatically.
Note that if you have selected
Video using H.221 aggregation (legacy)
as the call type,
you must ensure you select a bandwidth that matches the number of telephone numbers
that you have entered.
o
Encryption settings
:
Use transparent encryption
: when selected, the ISDN gateway will simulate
point-to-point encryption. That is, it will set the encryption state
(enabled/disabled) used on the received call as that to be used on the outgoing
call. That is, the ISDN gateway will attempt to match the encryption state for the
outgoing call to that of the incoming call. This means that if the encryption state
changes on either the incoming or outgoing call, the ISDN gateway will attempt to
change the encryption state on the other side of the call. This can be helpful if a
call starts as an encrypted call both sides of the ISDN gateway and then the
