I need help configuring a 1861 ISR. This SOHO will have 4 analog line or PSTN connecting to the router and want to be able to connect 4 Cisco Ip Phones 796X to this router and make VoIP calls out the local ISP and out the PSTN. I was wondering what will be needed so that I can implement VoIP using the Cisco 796x Series phones with 4 pstn lines and a local ISP connection so that calls can be forwarded out.
I have attached a configuration of an existing 1861 we have implemented but registered to our CallManager via CallManager Fallback. However I want this design to be independent and totally separate from our network.
