Daniel, Try Michal's suggestion first as it looks to be the easiest. The decode of the dump you supplied seems to be an RRQ not RCF which is strange as Quintum is a GW here and the last set of errors implied a decode not an encode. Looking at the message in Ethereal shows it to be an RRQ also. Error information returned from ASN.1 Encoder/Decoder complains about: D0081S: End of input reached before message was fully decoded; check field 'port' (type: INTEGER) of field 'ipAddress' (type: SEQUENCE) of element #5 (type: TransportAddress) of field 'callSignalAddress' (type: SEQUENCE OF) of field 'registrationRequest' It basically means that the end of the message was reached before expected based on the size and that the point at which this happened was in the 5th item of the CallSignalAddress list. The info decoded by Ethereal shows this 5th element with an IP=50.1.0.1 and no Port value. Verify that you are sending the correct hex dump (RRQ vs RCF) the trace just before the correct dump should look similar to: Decoded RAS Message Type RCF: --- Length = 51 --- <hex dump here> QEng7 ______________________________________________________ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/ ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________________ Posting: mailto:Openh323gk-users@xxxxxxxxxxxxxxxxxxxxx Archive: http://sourceforge.net/mailarchive/forum.php?forum_id=8549 Unsubscribe: http://lists.sourceforge.net/lists/listinfo/openh323gk-users Homepage: http://www.gnugk.org/
