                          <div bgcolor="#FFFFFF" text="#000000"> Hi
                            Anthony,<br>
                            We do this pretty frequently with a high
                            success rate. It really depends on the site
                            size and usage patterns.<br>
                            <br>
                            A couple of things to keep in mind:<br>
                            <ol>
                              <li>If its a 1-2 user remote office the
                                service profile is realy no different
                                than a residential user. Deploy
                                accordingly. <br>
                              </li>
                              <li>For higher user density sites we
                                usually will deploy some kind of edge
                                router (edgemarc / simplewan etc). A
                                small amount of QOS at egress goes a
                                long way on asymmetrical connections. <br>
                              </li>
                              <li>Abandon G711 where possible for a FEC
                                codec (Opus is my weapon of choice). A
                                tiny amount of packet loss or jitter on
                                Opus makes zero difference. A larger
                                amount of packet loss, which would
                                generate clicks and pops on G711 will
                                not be as noticable over Opus (and still
                                sound superior to most cell
                                conversations. If necessary transcode at
                                edge to support this. <br>
                              </li>
                              <li>Abandon standard ports. This is really
                                more about avoiding psuedo-intelligent
                                ALG's in the path for the 1-2 user
                                sites.<br>
                              </li>
                              <li>Be reasonable. Nobody is going to (ok
                                some will try but it should be advised
                                against) run a 200+ user shop on adsl. <br>
                              </li>
                            </ol>
                            I'm happy to discuss in more depth offline
