http://tec.myfortinet.com/04_sip_trunks/d_manage_inbound_call_routing/index.html Inbound call routing rules determine how FortiVoice handles external incoming calls that are not routed by a DID mapping. Rules can match the caller ID or called number and apply one or more call-handling actions. On the FortiVoice web administration page, select Call Routing and Inbound on the left-hand menu. Select the Inbound tab to manage inbound call routing rules. Select the incoming_default rule and click the Edit button to edit the inbound call routing rule. Hugo en-US
