SIP VoIP for Home and the Day of Sadness

Today is a sad day, because yesterday I came up with an evil super plan, however today I realise that it just cannot be.

My evil super plan was this. To purchase a SIP line from an ISP, configure my Cisco 2651XM with CME and have the SIP line trunked into the router. From here, I was going to replace our existing Windows Home Server with Windows Small Business Server 2008, which I would install Office Communications Server 2007 R2 onto.

The combination of SBS and OCS would give us the ability to use Unified Messaging (UM for Exchange) and would allow us to use the Office Communicator client on the desktop and Office Mobile Communicator on our Windows Phone devices. I would then have configure the 2651XM and OCS to trunk the SIP line between each other using guides available online for configuring OCS and CME to talk so that inbound calls on the SIP line would be routed to the OCS server.

This just gets better now, because the second part of the plan was to configure a hunt group in OCS which would group both me and Nicky together. If someone were to ring the home phone, it would ring both of us simultaneously and then the first one to answer receives the call (that’s the hunt group at work). If nobody answered then the caller could leave a voicemail on the OCS server which would be delivered to both me and Nicky to our SBS Exchange mailboxes using UM.

Just stop for one minute to think of the power and the feature set am talking about here?

  • Imagine being able to answer your home phone anywhere in the world from either your PC or mobile?
  • Imagine being able to receive voicemails left on your home phone from your inbox anywhere in the world via PC, mobile or Outlook Web Access from an Internet cafe?
  • Imagine making phone calls to numbers anywhere in the world just like using a normal telephone but at the fraction of the cost?
