Hello @Wash, you will have major problems with voip because the user is restricted to wi-fi zones and such public zones will not guarantee latencies for voip traffic, are so dependent of signal levels too. I tested a professional voip software application for handsets sometime early last year for a few months on travels and had a lot of issues with quality whether over grps or 3g, unless you can get g711 to work with stability. Most mobile operators will not guarantee voip over such networks because of the uplink capacity. I'd suggest you move him to a blackberry service for emails and let him add users on the blackberry instant messenger service for instant communications. HTHs. :-) On Sun, Dec 26, 2010 at 1:05 PM, Odhiambo Washington <odhiambo@gmail.com>wrote:
I hope some of you have been in such a situation. I have a roaming boss, travels everywhere and makes calls, calls and more calls! I am looking into a way of saving the expenditure on calls, especially those "roaming" charges. The problem is that he does not carry a laptop with him and is not tech savvy! It's not gonna be easy to handle this, but I am ready to get him any gadget that would make me save the telephone bills whenever he is roaming. I am thinking of a wireless handheld device that can make (and even receive) phone calls via a VPN connection. I have an enterprise class telephone system (Avaya) hosted somewhere and I also have a VPN service on a Cisco device that is connected to this phone. I can use IP Phones that have VPN capability. Can be SIP device too, though I'd love to get something that supports H.323 (or both)...
Anyone have bright ideas?
