it’s my first post on this list, I hope not to bore youwith my novice

We’re using a TDM400 with 3 fxo modules connected to pstn.
Call goes inbound/outbound correctly, after playing a bit on some
dahdi-channels.conf/chan_dahdi.conf options.

The “big” problem is that after 5 minutes and 16” of outbound call,

Does somebody had similar problems ?

Thanks in advance
