Dave,
Thanks for the offer of help but I need some more input into pricing before I contemplate going any further.
Looking around this board cisco 5300’s seem to be a popular choice but at 16k a box isn’t going to be viable for a smallish client list.
Bottom line is I need to know what the minimum hardware spec is to run 30 lines from a single ISDN line is plus the cost.
Alternatively if i don’t go for a bespoke voIP router what type of telephony cards + compression software would I need.
