Which voip package in pkgsrc works on NetBSD?

Following are what I tried till now, though none worked:

wip/linphone: Incoming calls work, though not outgoing. Tried building
with latest released version with no luck.

wip/twinkle: Compilation errors

comm/asterisk: Module load errors. (There is a separate mail thread on
this.)

I prefer command line which above ones offer, though since none of them
worked, tried the following:

pidgin: Could send only IMs, no voice calls.
flinch: Seems pidgin with just curses ui.


Is there anyone using voip successfully? If yes which package?
