Hi All I have my own business, we have two offices. One is in Glasgow and one in Sunderland. Neither as yet have a hardwired bb connection. In both I am using an ee 4g Alcatel Y800 router which is working pretty well for our internet needs. As a cost reduction measure (to reduce the mobile bills as we don't have land lines) I have been considering VoIP and getting into a bit of a pickle with the options. This seems to be challenging as I the Alcatel routers don't have internet connections etc. I do have a spare PC (low spec) which could handle the routing etc but there appears to be a plethora of hardware out there. I am not sure whether to get a new embedded sim router (eg D-Link DWR-921 Wireless-N 4G LTE Router w/ Embedded SIM (150Mbps or http://www.3grouterstore.co.uk/3G/2N_Speedroute_4G_Router.html) or just connect the computer via the wifi and use a dect system (UniData WPU-7800 Wireless Wifi VoIP Phone: Amazon.co.uk: Electronics I need two phones in Glasgow and four in Newcastle. We don't have any land line numbers at present either, so that using a VoIP number isn't an issue either. Finally, or perhaps round the wrong way, i need to look at the software to facilitate this too. Any suggestions gratefully received. I hope this makes sense, if not I would be happy to clarify any points.
