The cheap phones I like the best are the grandstream budgetone (around $65). I also have a supra spa-3000 for answering the POTS line and taking messages. (my motto: anything worth build is worth over-building. ;-)) I also have sipura spa-841, but the audio path is very noisy. I haven't had any show-stopper interoperability problems that a bit of playing with the options settings couldn't fix. I do use ulaw (standard US phone) encoding so that may help. Every phone and VOIP provider seems to do ulaw even if it may not be their preferred encoding. OB open-source: these phones follow the voip rfc's and can talk to open-source sip phones (unlike the proprietary stuff like skype which is in a world to itself.) -wolfgang -- Wolfgang S.
