Sorry, I don't use Radius in my systems and I don't know whether gnugk can be made to contact the Radius server when an endpoint unregisters. The manual says that RadAuth only works for RRQ, ARQ, and Setup. Perhaps Michal can comment on this. > one more doubt.

But if the plug was pulled for longer than the TimeToLive, then the GK knows that the ATA was gone, so when it comes back on line, the RRQ will look like a "new" registration, and the Radius server will be contacted, which I assume is what you want. --Stewart ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
