Appendix B – Gnu-gk Configuration Summary

This is a complete gatekeeper.ini file for an organisation wishing to connect to the JVCS-IP or a similar H.323 network. The file can be copied and pasted, edited, then saved in the openh323gk\bin folder. Comments can be added by preceding them with a # character for each line of comment. Where a value has ‘x’s substitute your own local details.
This configuration allows dial-out from the central JVCS-IP MCUs using E.164 (GDS) addressing and IP address. It also allows terminals in this gatekeeper’s zone to dial direct (out-of-service) using E.164 or IP. Remote terminals can dial in using IP address, but not using E.164 (assuming firewall configuration allows this).
