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.
Best regards
Heinrich
