Recently there has been an upsurge in articles about the benefits of hosted VoIP for SMBs accompanied by a similar upsurge in providers who offer such services.<br><br>While I understand most of the benefits highlighted, especially if the SMB is geographically dispersed; I can't seem to resolve one nagging dilemma in my head:
<br><br>Calls between local extensions situated within a physical location (a cubicle across the hall) must traverse over WAN. Isn't this very inefficient? And, doesn't it require a much higher WAN bandwidth, which is usually limited and expensive - very expensive in some countries?
<br><br>So, for a 20-user SMB with all its users located in a single office, all extension-to-extension (local) calls must go out on a WAN and come back to the office. This will require a much higher scarce WAN bandwidth and not use the abundant LAN bandwidth!
<br><br>Would hosted VoIP be a better choice such an SMB?<br><br>I would appreciate your thoughts on this issue to help sleep well :)<br><br>Thanks.<br><br><br><br>
