Hi, Just as we have a discussion about problems with cisco ATA186 devices I experience this following: Since cvs update last Sunday my ATA186's using 2.16 firmware with MGCP there does not seem to be any RTP happening. Rebooting the ATA's does not work. Strange thing is: I have a SwissVoice IP10S with MGCP that is working just fine with this same version of asterisk. Any thoughts ? Florian
