We currently have some old and hard to use Vina routers installed that allow us to send/receive calls and data between our remote site and our main site. The routers either have fxo or fxs cards in them depending on which site they are in.
At our end, a couple lines come off our PBX to the router along with a network connection and a T1. We have a T1 to the remote facility where it terminates into the router and splits the connection back out. (The remote facility has the fxs card.)
We would like to upgrade the equipment and use Cisco devices but I've been unable to figure out what hardware we would need and how to configure it.
We have considered using VoIP but we have reasons that we don't want to.
Can someone help?
Hi, VoIP means that the voice signal is digitalized, then encapsulated in an IP packet, and sent over an IP network. This is the current technology used by all cisco products with few exceptions.
As mentioned before I recommend an ISR router and not the IAD that is targeted for service providers.
The router can be as small as 2801 voice bundle, plus 2 x VIC-4FXS/DID, and WAN card as necessary.
Remember that you will always need something in the hub site as well, to reconvert VoIP to analog FXS, FXO or whatever interface you need to use.
