Header]
✔
SIP REGISTER message generated (created) by the
device: The device does not send REGISTER
messages to the proxy for this specific registration
process (i.e., Accounts table or User Information table)
during the timeout specified in the Retry-After header of
the 503 response. However, the device considers the
proxy as online and therefore, it continues sending traffic
of other entities to the proxy.
✔
All other SIP dialogs (e.g., INVITE): The device ignores
the Retry-After header and forwards the 503 response
transparently to the other user agent.
Defines the time (in seconds) used in the Retry-After header
when a 503 (Service Unavailable) response is generated by the
device.
The time range is 0 to 3,600. The default is 0.
Determines whether the device, upon receipt of a SIP 503
response without a Retry-After header, behaves as if the 503
response included a Retry-After header and with the period (in
seconds) specified by the parameter.
■ [0] Disable (default)
■ Any positive value (in seconds) for defining the period
When enabled, this feature allows the device to operate with
Proxy servers that do not include the Retry-After SIP header in
SIP 503 (Service Unavailable) responses to indicate an
unavailable service.
The Retry-After header is used with the 503 (Service
Unavailable) response to indicate how long the service is
expected to be unavailable to the requesting SIP client. The
device maintains a list of available proxies, by using the Keep-
Alive mechanism. The device checks the availability of proxies
by sending SIP OPTIONS every keep-alive timeout to all
proxies.
If the device receives a SIP 503 response to an INVITE, it also
marks that the proxy is out of service for the defined "Retry-After"
period.
Determines the device usage of the P-Associated-URI header.
This header can be received in 200 OK responses to REGISTER
requests. When enabled, the first URI in the P-Associated-URI
header is used in subsequent requests as the From/P-Asserted-
Identity headers value.
■ [0] Disable (default)
■ [1] Enable
Note: P-Associated-URIs in registration responses is handled
only if the device is registered per endpoint (using the User
Information file).
