Description

In cases where a SIP INVITE contains multiple Diversion headers, this setting specifies the order of priority in which the headers will be processed. By default (the "normal" setting), the value(s) in the first header will be considered first in the forwarding chain. When the setting is set to "reversed", the value(s) in the last header will be considered first in the forwarding chain.

This is useful for cases where the first number in a sequence of forwards is in the last Diversion header:

Diversion: <sip:8885551002@isp.com>;reason=unconditional
Diversion: <sip:8885551001@isp.com>;reason=unconditional

In the example above, the call has been first forwarded by 8885551001, then to 8885551002 which forwards to the final destination.
If the administrator wishes the "Fwd by" field on the screen when receiving a call to show the number in the last header (in this case the first number to forward the call), the setting should be set to "normal". If the number in the first header is preferred (in this case the last number to forward the call), the setting should be set to "reversed". This is useful for scenarios where the SIP server orders the Diversion values in a way that may be considered "reversed".
