We are a medium size business with about 300 users and one primary office location. We have a dedicated 100MB connection between our main site and the DR site (same subnet). We do real-time replication of data (SAN to SAN) and backups over that 100MB connection which usually stays around 10MB usage during the day. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Ultimately, we would like to place our Publisher and Unity Connection servers over at the DR site with a router (GW) so, that if we lost our main site we would still have our phone system. We currently have 4 T1s and are using MGCP. Would it be more beneficial to move to SIP or does it matter? Would this work or is there a better solution out there?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Our current phone system consists of:<o:p></o:p></p><p class=MsoNormal>2 - CUCM 6.1.2 (Publisher and Subscriber)<o:p></o:p></p><p class=MsoNormal>1 – Unity Connection 1.2(1) SR2<o:p></o:p></p><p class=MsoNormal>1 – Contact Center Express 5.0<o:p></o:p></p><p class=MsoNormal>2 – Cisco 3725 routers (total of 4 T1s) MGCP protocol<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any suggestions or feedback will be greatly appreciated. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>John<o:p></o:p></p><div class=MsoNormal align=center style='text-align:center'><span style='font-size:7.5pt;font-family:"Times New Roman","serif"'><hr size=2 width="100%" align=center></span></div><div><p class=MsoNormal><strong><span style='font-size:7.5pt;font-family:"Arial","sans-serif";color:navy'>Note:</span></strong><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:navy'><o:p></o:p></span></p></div><div><div><p class=MsoAutoSig style='margin:0in;margin-bottom:.0001pt'><span style='font-size:7.5pt;font-family:"Arial","sans-serif"'>This message and any attachments from the law firm Arnall Golden Gregory LLP may contain CONFIDENTIAL and legally protected information.
