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.

Forward = Use different call identifiers for a redirected INVITE
message (default).
ƒ
[1]
Redirect = Use the same call identifiers.
Enable P-Charging
Vector
[EnablePChargingVec
tor]
Enables the addition of a P-Charging-Vector header to all outgoing INVITE
messages.

Upon receipt of an ISDN SETUP message with redirect values, the device
maps the Redirect phone number to the SIP 'target' parameter and the
Redirect number reason to the SIP 'cause' parameter in the Request-URI.
Redirecting Reason >> SIP Response Code
Unknown >> 404
User busy >> 486
No reply >> 408
Deflection >> 487/480
Unconditional >> 302
Others >> 302
If the device receives a Request-URI that includes a 'target' and 'cause'
parameter, the 'target' is mapped to the Redirect phone number and the
'cause' is mapped to Redirect number reason.

503 (Service Unavailable) response is generated by the device.
The time range is 0 to 3,600. The default value is 0.

RIHeader]

subsequent requests as the From / P-Asserted-Id headers value.
