The way I understand the Linux ISDN maintainer, he is saying that your telco operator will protect you from that if the message comes to you over their network. But if asterisk-chan-capi is used in a PBX setup, where phones are connected to it (and asterisk is not only connected to phone lines, it _provides_ phone lines), then these phones are "local source" and can cause the overflow. Possibly (but there I'm unsure), if Asterisk (acting as a phone) and another phone are connected to the same line, that would count as a local source, too. >> If not, it probably doesn't need a fix for Etch. So this indeed needed a fix for etch, and got one. Closing that item in my personal TODO now. -- Lionel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
