Configuring Allowed Coder Groups

The Allowed Coders Group page allows you to define up to five Allowed Coder Groups,
each with up to 10 coders. Allowed Coder Groups determine the coders that can be used
for a specific SBC leg. Therefore, the device can enforce the use of specific coders while
preventing the use of other coders. Coders excluded from the Allowed Coders Group are
removed from the SDP offer. Only common coders between SDP offered coders and
coders configured in the Allowed Coder Groups are used. For more information, see
'Restricting Coders' on page 432.
The Allowed Coders Group table is also used to configure Extension coders. These are
coders that are added to the SDP offer. For more information on Extension coders, see
Coder Transcoding on page 432.
User's Manual
Defines the direction of the SIP request to which the rule applies.

[0] Both = (Default) Rule applies to inbound and outbound SIP
dialogs.

[1] Inbound = Rule applies only to inbound SIP dialogs.

[2] Outbound = Rule applies only to outbound SIP dialogs.
Defines the maximum number of concurrent SIP dialogs per IP
Group or SRD. You can also use the following special values:

[0] 0 = Block all these dialogs.

[-1] -1 = (Default) No limit.
Defines the maximum number of concurrent SIP dialogs per user
belonging to the specified IP Group or SRD. You can also use the
following special values:

[0] 0 = Block all these dialogs.

[-1] -1 = (Default) No limit.
Defines the rate at which tokens are added to the token bucket
per second (i.e., token rate). One token is added to the bucket
every 1000 divided by the value of this parameter (in
milliseconds).
The default is 0 (i.e., unlimited rate).
Note: The token bucket feature is per IP Group, SRD, SIP
request type, and SIP request direction.
Defines the maximum number of tokens (SIP dialogs) that the
bucket can hold. The device only accepts a SIP dialog if a token
exists in the bucket. Once the SIP dialog is accepted, a token is
removed from the bucket. If a SIP dialog is received by the device
and the token bucket is empty, then the device rejects the SIP
dialog. Alternatively, if the bucket is full, for example, 100 tokens,
and 101 SIP dialogs arrive (before another token is added to the
bucket, i.e., faster than that defined in the Rate field), then the
device accepts the first 100 SIP dialogs and rejects the last one.
Dropped requests are replied with the SIP 486 "Busy Here"
response. Dropped requests are not counted in the bucket.
The default is 0 (i.e., unlimited SIP dialogs).
Note: The token bucket feature is per IP Group, SRD, SIP
request type, and SIP request direction.
