SIP User's Manual
Determines whether the 'ptime' attribute is included in the SDP.
[0] = Remove the 'ptime' attribute from SDP.
[1] = Include the 'ptime' attribute in SDP (default).
Determines the device's behavior regarding call identifiers when a 3xx
response is received for an outgoing INVITE request. The device can
either use the same call identifiers (Call-ID, Branch, To, and From tags)
or change them in the new initiated INVITE.
[0] Forward = Use different call identifiers for a redirected INVITE
message (default).
[1] Redirect = Use the same call identifiers.
Enables the inclusion of the P-Charging-Vector header to all outgoing
INVITE messages.
[0] Disable (default)
[1] Enable
Determines 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 value 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 this
parameter.
[0] Disable
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.
Determines the SIP header used for the source number in incoming
INVITE messages.
'' = (empty string) Use the device's internal logic for header
preference (default). The logic for filling the calling party parameters
is as follows: the SIP header is selected first from which the calling
party parameters are obtained: first priority is P-Asserted-Identity,
second is Remote-Party-ID, and third is the From header. Once a
URL is selected, all the calling party parameters are set from this
