Call Forward

<note important>When a member is added to a line group (hunting), any call forwarding behaviour is ignored. This is to avoid the call from forwarded instead of going to another member</note>

• If the destination device is not registered
• If the hunting timeout with no one answering the call

• New features in v7, a message is displayed to inform of a CFA loop and provide a reorder tone.
• Previously this is prevent by CFA max hop service parameter

• New features in v7, when a CFA loop is detected and a CFNA is configured then the call is CFNA instead of drop
