Bug#597760: Test with SVN trunk

[Heinrich Ruthensteiner]

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 [s at 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
