Usage guidelines
If call forwarding is enabled, the SIP trunk device processes call forwarding information without notifying
the calling party, and does not transfer call forwarding information to the endpoints.
If call forwarding is disabled, the SIP trunk device transparently transfers the call forwarding information
sent from the called party to the calling party, and notifies information about the calling destination to the
calling party so that the calling party re-sends a session request to the called party.
