All, Any suggestions on the following? We have a Grandstream FXO gateway where a call is sent to and I receive a 180 rinigng followed by a 200ok message but the line plays back an audio busy message. Any ideas how to force a fail over / continueation in the dial plan in this situation?     Jason Holden   Phone: 1-866-836-9198 X405 Direct: 7868009949 www.thinksimplicity.com <http://www.thinksimplicity.com>
