hello, I downloaded gnugk-2.0.8 and built it on Linux REDHAT 9.0, kernel 2.4.24. i then used the command ./gnugk -tt r in order to run the gatekeeper. On the callee side i used: ./ohphone -u callee ......... -a -l It registered with the gatekeeper and was listening for an incoming call. On the caller side i used: ./ohphone -u caller ............. -p OpenH323GK@{domain_name} callee It worked fine for sometime, establishing calls between users "caller" and "callee". however, after sometime, it wudnt work. On trying to give the IP of the gatekeeper with ./ohphone -u caller ............. -g {IP} -p {IP} callee Now it worked fine...but this is not the intended procedure. i dont want to provide any IP address in the command! Please let me know if you know of any solution to this... Thanks & cheers, Santanu ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
