Hi, Thanks Brian. As you said the cisco tries the codec one by one. When i only enable codec that can be supported i have no sound problem. Thanks. Question though, As you suggested i would like to use the g729 codec but before i purchase it from digium can i have a sort of demo version? Also do i have an easy way to install the codec under FreeBSD? It was tough enough to install asterisk even with the FreeBSD ports. BTW for the $10 per channel should i consider $10 for H323 channel $10 for the SIP channel (for instance), or is it $10 per number of concurrent calls wanted regardless of the protocols used?
