for people with SIP phones, maybe better codecs can be used. So I also believe that VOIP is a viable option for a pro situation, and I would prefer to use the Linphone software because of its command line client (which useful for automation and integration), and there's probably other free options.
In a profesional situation, asterisk might be better (perhaps on it's own machine) as it would provide for a switch board as well. On the same number you could have more than one person call in as the number is only used in sip to initiate the call. Plus, it does have a jack interface. I have not played with asterisk myself, so I don't know how easy it would be to set up. The main thing with any of these solutions... SIP or a local phone number limits you to local callers or people with sip clients. Skype, like it or not, has infected more computers than most virus have... so using skype gives you the world. For an Inet radio station... this is best.
Another consideration with Inet radio stations is that often the stream server does not belong to the studio operator and the studio operator does not have an IP that is visible. It is possible to do ip to ip voip/sip calls so long as one end is visible no server is needed, but for a lot of people that is not the case... and even if it was, not that many people would know how to use it. So it would be fine for remote news gathering with trained people, but not casual call in.
