We use to have 2 PRIs (One for local and one for LD). Moving to SIP was a cost savings for us because we were way underutilizing our PRIs. We had the need for a robust data network to run some customer facing web based applications, so even though all of our eggs are in one basket so to speak, there are at least 3 ways for data to travel from our office, to our collocated network, and then to the Internet where we connect to our SIP provider. In case all of that fails, then we have 911 fail back to a POTS line. We have spent a good bit of capital to beef up our network over the years, mainly to support VoIP, however, the rest of our data traffic benefits from these upgrades, so we felt it was worth it. Our calculations showed that we would get a 5 year ROI from the savings that we incurred from moving from PRI to SIP/Cisco VoIP. Once of those savings was a smaller maintenance contract from our Lucent PBX to a Cisco ISR. Not to mention that our phone system took up an entire wall in our Datacenter, and now it consumes 3U of rack space.<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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Also, we have a smaller system at our collocation site that can intercept calls automatically if our main Cisco CME system is not online. This is something that we could not have do before with our PRIs for DR/BC since if our building burned down, we would be SOL since the PBX would have gone with it.<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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>We chose Cisco over other less expensive solutions because we had already a large investment in Cisco switches and routers. Cisco is a name we trust, and it is a single point of contact for network/phone issues. Our biggest expense was the IP phones themselves. I think the success with SIP and VoIP depends mainly on how reliable the SIP provider is and if your VoIP network internally is in good shape. When we moved to SIP/VoIP in 2009, our SIP provider at the time had issues with their network, and after a year we canned them. It was a black eye for our VoIP “system” because EUs did not understand the complexity of phone systems and networks. We now have a SIP trunking provider that has a 99.99% SLA, and after over a year with them, we have yet (knock on wood) to have a single issue with our SIP service. It also works great with our Cisco ASA firewall.<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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>So I guess my point is, that it is not always about just money. It can also be about reliability, customer service, and making it easier for our EUs to do their job. They love our unified messaging system (Unity) and how they can access voice messages with their Blackberries and iPhones.<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><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Just my 2 cents. <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><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> cisco-voip-bounces@puck.nether.net [mailto:cisco-voip-bounces@puck.nether.net] <b>On Behalf Of </b>SouthEastTexasTelecom<br><b>Sent:</b> Sunday, September 25, 2011 4:48 PM<br><b>To:</b> 'cisco-voip'<br><b>Subject:</b> Re: [cisco-voip] Moving to SIP<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Personally I cant see the need to change from ISDN PRI to SIP anyway..
