It is very difficult, time consuming and expensive in terms of being charged by the local PTT to write and debug code to decode this type of messages (which i did partially to get AOCD and AOCE decoded) and this is the cause isdn4bsd is not able to decode them. More, i don't see any advantage i get if i would be able to decode those messages (there are a few conditions, why CCBS - Completition of Call to Busy Subscriber - is only possible between some selected - but growing - number of users). But - as usual - i'll happily accept diffs if someone likes to decode those messages! (btw: in case someone likes to know what they are, there is a web-based ISDN message decoder at http://www.ch.engelschall.com/u/martin/webdecoder/webdecoder.cgi nice !) > Aug 28 19:26:39 foobar /kernel: i4b-L3-i4b_decode_q931: cannot find calldescriptor for > cr = 0x0, crflag = 0x0, msg = 0x62, frame = 0x62 0x1c 0x33 0x91 0xa1 0x30 0x2 0x2 0x40 ^^^^^^^^^^^^^^^^^^^^^^ These messages have either a global or dummy call reference, these type of messages should not being displayed anymore by recent i4b versions (i don't recall when i changed this). > I dont really mind seeing these messages, but shouldnt i4b rather > correctly interprete these messages and print out some > appropriate info ?

There are many, many features isdn4bsd has not the slightest idea of. hellmuth -- Hellmuth Michaelis hm@kts.org Hamburg, Europe A duck is like a bicycle because they both have two wheels except the duck (terry@cs.weber.edu) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
