As system administrator, monitoring the continuity of services is vital. Today I would like to highlight some tools that could come in handy for VoIP monitoring.


For those of you who didn't know it, Nagios can be configured to monitor pretty much anything you want, including Asterisk servers. Actually, with Nagios the (much) harder part is deciding what’s relevant to monitor, and what your alarm thresholds should be set at. Some VoIP community members have reported that they used Nagios to monitor ~4,000 hosts and about 8,000 to 10,000 services before they started running into scaling problems on a single box. For…

TDM410 and DSL


Hi all,
I have a system installation in Guam with two trunks. One has a DSL service
riding on it with the usual filter. That channel however keeps throwing
alarms. I bypassed the filter and it stopped throwing alarms, but of course

came back. Any suggestions? Could I have a bad DSL modem? Cassius
