[Asterisk-Users] why even use SIP

> 5) MWI, Call Waiting, 3-way calling missing
If I remember correctly (only used an IAXy a couple of times), it uses
shutter-tone to tell you when there's a message waiting

It definitely support Call Waiting : just use "Flash" as with normal
call waiting on the PSTN

Never tried 3-way calling, but I think it supports it

I compiled iaxprov on Cygwin, works nicely. There's somebody on this
list that made a Windows version to provision it. Works nicely, GUI
interface, can even scan the LAN to find IAXy. Here is the link to it

No it doesn't. Granted it has a couple shortcomings, but nothing that
bad. If Digium can fix the most important ones and find a way to drop
the price a bit, this would be a great little device.
