That really looks like some sort of garbage on the line (although is not strictly only garbage since they seem to be valid HDLC frames). How often do you get this? the word "frequently" means nothing from an engineering point of view. Every minute you get a burst of these? or is it a constant flow? can you receive/place calls despite this message? Try taking a pcap file when you're receiving those messages: http://wiki.sangoma.com/wanpipe-wireshark-pcap-pri-bri-wan-t1-e1-tracing Moises Silva Senior Software Engineer, Software Development Manager Sangoma Technologies Inc. | 100 Renfrew Drive, Suite 100, Markham ON L3R 9R6 Canada t. 1 905 474 1990 x128 | e. moy@sangoma.com
