I’m beginning to wonder if the key isn’t interoperability, but interworking. nteroperability would be the ability to plug any SIP/IP communications device into any other, and have them work together. That’d be terrific, of course, but it’s more complicated than just presence federation–and presence federation is pretty complicated, itself. Interworking would be at once a more modest and potentially more useful goal. For the foreseeable future, we’re going to be communicating over diverse overlay networks–not just a mix of TDM- and IP-based communications in the enterprise, but more importantly, public cellular as well. If an enterprise could tie together all of these diverse components, it could exercise greater control over its cellular costs (and assets, such as phone numbers) and provide more efficient communications to its mobile workforce. The core of such an interworked systems is…well, it’s a PBX, probably an IP-PBX.
