We are less than a month from go live on RC and I'm still fighting trying to get AudioCodes MP-124 devices to work properly with RC. I get the analog ports to show as registered both on the Audiocodes as well as on the RC side. But every time I lift a handset, I get nothing but a fast busy as soon as it is lifted. The logs on the AudioCodes shows constant rebuilding of the outbound proxy connections, so I believe that is where the problem originates, but nothing I've tried seems to help with this issue.
Does anybody have experience getting these to function properly
