The good news: The system was stable during longer incoming calls. It is no longer frozen during the tests (about one hour). It was possible to answer the call with the ISDN- as well with a SIP-Phone
Not so good: I was not able to establish outgoing calls from the plugged in ISDN-Phone: When I tried to call any number the CLI told me the following: [Sep 27 18:01:19] WARNING[2766]: chan_dahdi.c:13015 pri_dchannel: Unable to set gains on channel 5 -- Accepting call from '' to 's' on channel 0/2, span 2 -- Executing [...@reception:1] WaitExten("DAHDI/5-1", "3") in new stack -- Timeout on DAHDI/5-1, continuing... . . . == Spawn extension (reception, s, 2) exited non-zero on 'DAHDI/5-1' [Sep 27 18:01:26] WARNING[2844]: chan_dahdi.c:2858 restore_gains: Unable to restore gains: Invalid argument -- Hungup 'DAHDI/5-1' The phone did not identify himself and the system could not identify the called number. Maybe this "Unable to set gains on channel 5" or "Unable to restore gains: Invalid argument" could be an indication for the reason.
