Hello, i’ve some problems with dahdi.
From time to time the,
/etc/dahdi/system.conf changes to default
/etc/asterisk/chan_dahdi_groups.conf
/etc/asterisk/chan_dahdi.conf
configuration changes.
The files I’ve never edit manually. Only over the FreePBX web.
But, if the configuration goes lost then i have a backup and import the old configuration files to ne new one’s.
After all i stop Astersik and Dahdi manually and then i start first Dahdi and then asterisk.
This Workaround will work for me.
In addition, our Echo-canceler is MG2 but on the first installation it was the OSLEC canceler. The MG2 still fine, but why it changed? What is the difference between the two?
