AudioCodes Mediant 3000 User Manual

Version 7.0 907 Mediant 3000
User's Manual 58. Configuration Parameters Reference
Parameter Description
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.
Enable P-Associated-URI
Header
[EnablePAssociatedURIH
eader]
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).
Source Number
Preference
[SourceNumberPreferenc
e]
Determines from which SIP header the source (calling) number is
obtained in incoming INVITE messages.
 If not configured or if any string other than "From" or "Pai2" is
configured, the calling number is obtained from a specific header
using the following logic:
a. P-Preferred-Identity header.
b. If the above header is not present, then the first P-Asserted-
Identity header is used.
c. If the above header is not present, then the Remote-Party-ID
header is used.
d. If the above header is not present, then the From header is used.
 "From" = The calling number is obtained from the From header.
 "Pai2" = The calling number is obtained using the following logic:
a. If a P-Preferred-Identity header is present, the number is
obtained from it.
b. If no P-Preferred-Identity header is present and two P-Asserted-
Identity headers are present, the number is obtained from the
second P-Asserted-Identity header.
c. If only one P-Asserted-Identity header is present, the calling
number is obtained from it.
Notes:
 The "From" and "Pai2" values are not case-sensitive.
 Once a URL is selected, all the calling party parameters are set from
this header. If P-Asserted-Identity is selected and the Privacy header
is set to 'id', the calling number is assumed restricted.
[SelectSourceHeaderForC
alledNumber]
Determines the SIP header used for obtaining the called number
(destination) for IP-to-Tel calls.
 [0] Request-URI header = (Default) Obtains the destination number
from the user part of the Request-URI.
 [1] To header = Obtains the destination number from the user part of
the To header.
 [2] P-Called-Party-ID header = Obtains the destination number from
the P-Called-Party-ID header.
Enable Reason Header Enables the usage of the SIP Reason header.
