I started working on the voice/video over IP project and considering about the hardware needed. From Cisco, they have IP/VC 3520 boxes acting as the gateways between the IP network and the PSTN. However, it seems they also have modules for Cisco 2600/3600 that act in the same manner as those IP/VC 3520. Do you think I can substitute these modules with the IP/VC 3520 so that I can convert my IP network to PSTN for voice and video (said, conference room...)??? What models should I use for 2600 and 3600? Thanks All! Thomas N.
