Hello We are using Cisco IP-telephones. (VoIP) Cisco invented just another proprietary protocol they call 'the skinny protocol'. It seems as if skinny is H.323 for the poor man. They build up a control connection over tcp port 2000-2002 and negotiate a high udp connection for the voicestreams. We have to bring skinny through FW1. It seems as everything is working, but if somebody in the remote location presses the hold button to forward a call, the connection gets lost. Does somebody know if cisco requires anything else? Does Checkpoint care about skinny? regards -- Hans-Joachim Hoetger voice: +49-5246-80-1555 mediaWays GmbH fax: +49-5246-80-2555 PGP: BA D3 11 1A 40 EB 29 35 D9 E2 84 5F 13 55 1E D3 07 6E D9 77
