Also, while now the ISDN link is up, and we are able to make some calls
thru the new line, we have two error messages
going on the asterisk console:

When asterisk start, or when the PRI reset, every channel trigger this
message:
[Jan 19 21:01:17] ERROR[13512]: chan_dahdi.c:8413 dahdi_pri_error: !!
Unexpected Channel selection 3
   -- B-channel 0/1 successfully restarted on span 2
[Jan 19 21:01:17] ERROR[13512]: chan_dahdi.c:8413 dahdi_pri_error: !!
Unexpected Channel selection 3
   -- B-channel 0/2 successfully restarted on span 2
...
And this one:
    "Unable to handle return result on switchtype 5!"
happen on a regular basis, i'm not sure but it look like jsute before
the outgoing call is bridged to the internal extension.
