We can put about 9/10 calls using SIP/gsm through our BT Business Network ADSL package connection (832kbit upstream, £65/month) before you notice the quality starting to drop, but you could always get two connections and bond them together into one using openvpn or some other method if you wanted to. 2009/3/17 Gordon Henderson gordon+aster...@drogon.netgordon%2baster...@drogon.net On Mon, 16 Mar 2009, Gavin Henry wrote: Dear all, I'm currently researching options for a MT asterisk gui/system for a small business centre that will have 12 units in it.
