Network Jitter Level
Determines how jitter buffer size is adjusted by the ATA device. Jitter buffer
size is adjusted dynamically. The minimum jitter buffer size is 30 milliseconds
or (10 millis current RTP frame size), whichever is larger, for all jitter
level settings. However, the starting jitter buffer size value is larger for higher
jitter levels. This setting controls the rate at which the jitter buffer size is
adjusted to reach the minimum. Select the appropriate setting:
low
,
medium
,
high
,
very high
, or
extremely high
.
The default is
high
.
Jitter Buffer Adjustment Controls how the jitter buffer should be adjusted. Select the appropriate
setting:
up and down
,
up only
,
down only
, or
disable
.
The default is
up and down
.
Field
Description

Port number of the SIP message listening and transmission port.
The default is

.
SIP 100REL Enable
To enable the support of 100REL SIP extension for reliable transmission of
provisional responses (18x) and use of PRACK requests, select yes. Otherwise,
select no.
The default is
no
.
EXT SIP Port
The external SIP port number.
Auth Resync-Reboot
If this feature is enabled, the ATA device authenticates the sender when it
receives the NOTIFY resync reboot (RFC 2617) message. To use this feature,
select yes. Otherwise, select no.
The default is
yes
.
SIP Proxy-Require
The SIP proxy can support a specific extension or behavior when it sees this
header from the user agent. If this field is configured and the proxy does not
support it, it responds with the message, unsupported. Enter the appropriate
header in the field provided.
SIP Remote-Party-ID
To use the Remote-Party-ID header instead of the From header, select yes.
Otherwise, select no.
The default is
yes
.
SIP GUID
This field is not available with the PAP2T. The Global Unique ID is generated
for each line for each device. When it is enabled, the ATA device adds a GUID
header in the SIP request. The GUID is generated the first time the unit boots
up and stays with the unit through rebooting and even factory reset. This
feature was requested by Bell Canada (Nortel) to limit the registration of SIP
accounts.
The default is
yes
.
