This is particularly important because potential employers need a way to call me. Most people don't know what VoIP is and those that do seem to only know about Skype. My experience with skype has been of intentionally deceptive advertising and billing practices, terrible and extremely slow support, an awful (admittedly beta) Linux client and arguably poor voice quality. Although finding an open source SIP client such as Ekiga has proven easy and encouraging finding a good SIP provider that gives me the features that I want has been difficult. I need to be able to call people on PTSN and even more importantly I need a static phone number that people can call me on and leave a message even when I'm not logged on. What have slashdoters experience been with various VoIP providers and who do you prefer? Also what are your favorite clients?
