I am just reporting ivr success story with avaya multivantage through h.323 Initially, I used inaccess driver 6.3a. Asterisk IVR worked with netmeeting. However Avaya uses g711 codec and inaccess driver has problem with g711 and dropped call. So I switched asterisk cvs nufone module and it successfully worked without codec problem. thanks, jong ________________________________________________________________________________ ?? 100MB, ? ?? ?? ???? - ??! ??
