I have a Cisco 2621XM, a DSP Module, a a 7960G IP Phone and a FXO Card. I want to connect my phone line at home to my Cisco Router then call from my VOIP phone to a analog on the PSTN and then receive calls from the PSTN that will ring my VOIp phone through my router. Can anyone give me an idea on how to setup the config to make this work? I have already connected the equipment. Thanks.
