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.

This could be a good feature to add to the dahdi_maint utility. > What would be the correct ioctl definition ? DAHDI_MAINT seems not to be the right
You could add an additional context in the DAHDI_MAINT ioctl handler of your
base card to set/unset the yellow alarm bit in the framer. For an example, see
the Yellow Alarm handler in t4_check_alarms() and the DAHDI_MAINT…
Sometimes calls on Asterisk fail to connect to DAHDI channels and giving

congestion) There are 8 E1 connected on server and only 15-20 simultaneous calls. All
channels and E1 are showing in service without any alarms. Could anyone please let me know why this is happening? Thanks
I am reading through Sangoma Wiki right now. But someone may already and
quickly notice this. I have a system that is down since the morning (maybe
power intruptions). All seems fine except for "wanrouter status" shows

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

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