Last time we discussed our initial testing with Skype, an Internet-based point-to-point VoIP application. And our initial take was most positive. In fairness, though, we have to point out what we haven\u2019t tested yet.First, we were using our broadband access, so we haven\u2019t tested this over a dial-up connection. Maybe the quality and delay won\u2019t degrade; we just don\u2019t know yet. In reality, with the proliferation of cable\/DSL access for the work-at-home crowd, we don\u2019t see this as a major factor either way. We likewise have not had a chance to try international calls. (Our initial test was between Larry\u2019s office in California and Steve\u2019s in North Carolina.)We also found that headphones and an attached boom microphone were critical to avoid having predictably unacceptable echo. The application isn\u2019t magic, and it can\u2019t turn a PC speaker and a microphone into a conference-room speakerphone.We\u2019ve made a few calls, and all had good quality. On one occasion, though, after roughly 45 minutes, the connection dropped. Repeated attempts to reconnect produced strange results, but the problem disappeared once Larry rebooted his PC.One of the most intriguing capabilities that we want to investigate further is conference calling. Since there were only two of us, it was difficult (to say the least) to test a conference call with three or more parties. That\u2019s on our \u201cto do\u201d list, and we\u2019ll let you know how it works out.At this point, there is no videoconferencing or application collaboration capability. We\u2019re guessing that might be an add-on in a paid version of the software. There is, however, messaging built into the interface.In our view, these deficiencies are rather minor. In fact, they\u2019re so minor that we\u2019ve started using Skype as our preferred method to chat with each other.Next time we\u2019ll share some thoughts on the impact Skype and similar applications may have on corporate telecommunications.
