Hi, I got exactly the same configuration. take a look on: http://www.botka.homeunix.org/VoIP/insufficientbandwidth.html and change the ConnectMode in your ATA configuration. Take care that your other endpoint does not use H323V2 FastConnect when initiaiting a connection. If so, disable it. If this does not work send your ATA and GnuGK syslog and configuration.
