Call Forward

For analog interfaces:

The following methods of call forwarding are supported:

Three forms of forwarding parties are available:

●

When call forward is initiated, the device sends a SIP 302 response with a contact that contains the phone number from the Call Forward table (see Configuring Call Forward) and its corresponding IP address from the routing table (or when a proxy is used, the proxy’s IP address).

●

For receiving call forward, the device handles SIP 3xx responses for redirecting calls with a new contact.
