Hi Kenneth, my guess would be that this is either a network config issue or an issue with the PTLib version used to build the executable: It seems the Setup message from your gateway never reaches GnuGk, even so we can see the endpoint trying to establish a connection in the Wireshark trace. Also notice the error message in your trace: Toolkit.cxx(3504) GK Address 2002:5443:4300:1:0:1011:c0a8:6528 not found in the PTLib interface table I would suggest you check your network configuration and then take the latest GnuGk CVS code and compile it with the latest PTLib 2.12.x to see if the issue goes away.

The gnugk gatekeeper does not respond to the open signaling channel message after responding with an ACF. Attached are the log file, the configuration file, and a Wireshark trace showing the problem. What did I miss in the configuration? > > > Thanks. ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
