•
The default packetization period (ptime) for the transparent coder is 10
milliseconds. Using the SDP attribute ptime can change this.
•
The packetization period for Bypass Fax mode is the same as the packetization
period used for voice. If this bit is not set, the packetization period for the Fax
Bypass is taken from the ini file.
•
When sending a notification transaction request, the Mediant 1000 does not mark
it as optional.

MEGACO Termination Naming

The basic entities controlled by MEGACO protocol are called Terminations. Physical
Terminations represent a physical entity and ephemeral Terminations represent the
stream. Ephemeral Terminations exist only during a connection. From version 4.4, the
terminations names are defined by a new set of pattern parameters, as described in the
next section. Backward Compatibility is kept for the previous Terminations. (Refer to
''Backward Compatibility'' on page 110.)
7.2.6.1

Termination Name Patterns

Each termination type name is defined by an ini file or SNMP parameter. The pattern may
contain acceptable characters as defined in MEGACO. The '*' character is used to
represent the place where a digit should be. Therefore, it can not be part of the name itself.
All other characters, including slash, are considered text.
For example: The pattern "gws*c*" matches the termination name "gws0c1" and also
"gws10c20". The trunk numbers, in this case, are 0 and 10 and the channels are 1 and 20.
PHYSTERMNAMEPATTERN - Pattern of the physical terminations.
LOGICALRTPTERMPATTERN - Pattern for ephemeral terminations based on RTP
stream.
The starting number of each level can be controlled by a set of parameters:
EP_NUM - Controls the numbering of the physical terminations name pattern
EP_NUM_0 - Defines the starting trunk number
EP_NUM_1 - Defines the starting channel number
RTP_NUM - Defines the starting number for the RTP terminations. (The default is 0)

Old Termination Naming Method

Physical Termination names have up to three components: Gateway (in this case the
Mediant 1000) name, Trunk name and Endpoint name (for non-trunking gateways, the
trunk field does not exist).
Ephemeral Termination names have two components: The gateway name and a constant
string - 'RTP/' for RTP terminations and 'ATM/' for ATM terminations. So assuming that the
Mediant 1000 name is 'gw', if the first ephemeral Termination is of RTP type, it is called
'gwRTP/1', and if it is of ATM type, it is called 'gwATM/1'.
