I made a quick look at some of the V76 stuff in packet-h245.c and compared with the ASN.1 specification for H.245 version 9 at Packetizer, but I couldn't find any abvious mistakes in packet-h245.c. http://www.packetizer.com/iptel/h245/h245_asn.html But of course I may have missed something, Do you know what version of the H.245 specification the implementation is based on? Could it be that some stuff is later than the version 9 specificion? I will try to run the packets through some other tool I have later this week and compare the results I get. Below is an extract for from the ASN.1 specification : ======================================= V76LogicalChannelParameters ::= SEQUENCE { hdlcParameters V76HDLCParameters, suspendResume CHOICE {noSuspendResume NULL, suspendResumewAddress NULL, suspendResumewoAddress NULL, ...}, uIH BOOLEAN, mode CHOICE {eRM SEQUENCE {windowSize INTEGER(1..127), recovery CHOICE {rej NULL, sREJ NULL, mSREJ NULL, ...}, ...}, uNERM NULL, ...}, v75Parameters V75Parameters, ...} V76HDLCParameters ::= SEQUENCE { crcLength CRCLength, n401 INTEGER(1..4095), loopbackTestProcedure BOOLEAN, ...} CRCLength ::= CHOICE {crc8bit NULL, crc16bit NULL, crc32bit NULL, ...} ====================================== _______________________________________________ Ethereal-users mailing list [EMAIL PROTECTED] http://www.ethereal.com/mailman/listinfo/ethereal-users
