These are indicated on the codec by arrows either side of the setting, e.g.
P-
Point
. To restore Factory Default Settings select [Menu] > [Reset Functions]
> [Set Sys Defaults] > [All Profiles] > [Yes] and wait 10 seconds. Reboot the

11.4.3.
ISDN Line Types
The ISDN Line Types, ‘P-Point’ (Point-to-Point) & ‘P-Multi’ (Point-to-
Multipoint), are designated by the network service provider and may vary
between venues and locations.
Another ISDN setting is ‘On Demand’. This may be designated ‘On’ or ‘Off’
by the network service provider and is also discussed further below
11.4.4.
Session Data
By default, when
T
ieline
codecs establish communications the dialing codec
sends its settings to the remote codec over
T
ieline
Session Data. The
receiving codec inherits the following settings from the dialing codec:
•
Profile;
•
Algorithm;
•
Sample Rate; and
•
Bit rate.
This does not occur when dialing to non-
T
ieline
devices so ‘Session Data’
must be turned off to provide compatibility. To disable ‘Session Data’
navigate to: [Menu] > [Configuration] > [System Settings] > [Session Data] >
[Disable]. Note: Remember to re-enable ‘Session Data’ when dialing to
another
T
ieline
codec.
