Some of my customers use VoIP phones and/or Microsoft Lync for communication, including Instant Messaging and video calls. I want to recover their servers in my data center and allow them to continue using VoIP and/or Microsoft Lync.
I have everything in place to restore all servers, but I'm concerned that just the servers won't be enough -- what network gear or circuits, if any, would be required to make the above work? I already have redundant Internet connectivity and firewall protection, but I don't want to have to pay to have a SIP circuit run to my data center, and I prefer not to have to host a lot of customer-specific network gear.
In order to provide proper MS Lync and/or VoIP functionality, would I have to have a handoff with the Local Exchange Carrier (LEC) or other carrier into the data center? What might such a handoff look like (such as what equipment would facilitate this handoff, if required)?
