I am more comfortable with SIP trunks for small sites. It also have to do with what type of connection your last mile is. If you got fiber to the prem, then BW really will not be as big of an issue, as opposed to have a couple of T’s.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>Dennis Heim<br>Network Voice Engineer<br>CDW Advanced Technology Services<br>11711 N.
