[Asterisk-Users] TDM card loses Dial tone

[Youness El Andaloussi]

I experienced similar problems too with a 4 chan tdm400. This seems to 
especially happen when you make configuration changes. It has nothing to do 
with runing X or no, it does not even have to do with redhat... I 
experienced the same problem on mandrake.

One thing you have to be extra careful is when restarting, make sure that 
all the modules have entirely reloaded before expecting a dialtone with an 
asterisk debug console "asterisk -rvvvv"... many of the times I thought 
there was no dialtone and the asterisk process had gone cukoo, I noticed 
that configuration was not entirely reload.

Yet, reloading many times seems to get some of the TDM400 channels 
hung.  On the other hand, this problem does not seem to happen as 
extensively when no reloads are made
