I'm dialin out using location ips-doo:
dial ips-doo
Starting dial to location ips-doo using S1
ljubljana4> S1: Sending Call Request - 1502820
S1: Received Call Confirmation
S1: Received Disconnect Dest Out of Order (B2 ID:8002)
S1: Sending Disconnect Request
S1: Received Clear Conf (B2 ID:8002)
The "Dest Out of Order" happens because this is EuroISDN and the
destination has MSN (multiple subscriber number). When a certain device
returns BUSY, there could be other devices on the same bus that could
accept the call, so the switch waits for some time (a second or two) to
see if anything else responds. If not, you don't get a busy, but the same
tones you get when you call a nonexistent number. I'm not sure what kind
of switch is on both sides, but I would guess a Siemens EWSD, because
that's what 90% of switches here in Slovenia are.
I would expect after the call fails, that the corresponding S port on the
Portmaster would be free. But after the above, I get:
ljubljana4> show sess
...
S1 ips-doo - Netwrk Out CONNECTING 0 0
...
We're running ComOS 3.8.2.
Also, I have a callback setup in the other direction for myself, i.e. when
I call the Portmaster, it refuses the call (through call-check) and then
calls me back. But although the portmaster is ALWAYS dialing out to me (it
never knows my username on incoming calls, because it refuses the call
before PPP negotiation even starts), I can sometimes see multiple (!!)
_incoming_ sessions with my username stuck on the portmaster, i.e.
S5 blaz - Netwrk In CONNECTING 0 0
...
S9 blaz - Netwrk In CONNECTING 0 0
...
I haven't seen this in a couple of days, but then some days come when even
4 or 5 of this sessions are stuck, and it seems like they don't disappear
by themselves, I usually reset them manually.
I remember having problems with dialouts earlier (don't remember details
though) and this problem was fixed after a debugging session with Lucent
in some later revision of ComOS, but it almost seems like it has not been
completely fixed or like this is a related problem.
