It was of course just bad humor, I love both projects for what they are, and I agree that both have their own advantages and inconvenients.
For example, accessing that same conference from a dahdi card could be another goal where Asterisk would be at an advantage, as chan_dahdi is still superior (in the more tested sense) than openzap+mod_openzap. I just use both projects separately or together depending on what's needed! I'm no banker nor do I understand the code, but many thanks for all those unpaid contributions providing an excellent alternative for free telephony. Your names really deserve being engraved in google's cache for eternity. :-) But still, I would like to see those numbers... François.
