On the other hand it might be a bug or malfunction in the exchange or PBX you are connected to. SABME is used to setup a layer 2 connection and this error says that an SABME was received while the connection is already there. Since you can obviously reproduce it, perhaps you can try fix it ? :-))) You'll find all the details about this in the ETS 300 125 available free of charge from www.etsi.org. hellmuth -- Hellmuth Michaelis Tel +49 40 55 97 47-70 HCS Hanseatischer Computerservice GmbH Fax +49 40 55 97 47-77 Oldesloer Strasse 97-99 Mail hm [at] hcs.de D-22457 Hamburg WWW http://www.hcs.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
