Lines alarm not raised

[petr.necas]

We have a site with lots of SIP devices and the alarms treshold settings is as following:

---------------+--------+-------+-------+-------+---------+---------+----------
               |Total In|      Unavailable      | Alarm Threshold Percentages   
   Category    | System | Total |    %  | Alarm |  MINOR  |  MAJOR  | CRITICAL 
---------------+--------+-------+-------+-------+---------+---------+----------
Lines          |   390  |     0 |   0 % |       |   > 0 % |    20 % |   100 % |
Trunks         |     8  |     0 |   0 % |       |   > 0 % |    10 % |   100 % |
Receivers      |    48  |     0 |   0 % |       |   > 0 % |    25 % |   100 % |

All the SIP devices went down recently (probably due to a network issue) but no Lines alarm was raised. When looking into an online help for Lines alarm:

Indicates the amount of stations unavailable as a percentage (%) of the system total. The following are included in the line total:

    All DNI set devices with a programmed DN in the Multiline Sets, Single Line Sets, and Console forms. For IP devices, this also includes Hot Desk Users

All the SIP devices are programmed in Multiline IP Sets, so am I missing something?

I suspect that the only thing that will cause it to go into alarm is if you ManBusy an extension.
In the olden days, if you disconnected a bunch of DNI phones, it wouldn't go into alarm.
If I remember right, if an analog extension stayed off hook for too long and got locked out, it might raise an alarm.
Or if you had defective hardware on analog and DNI phones.
Other than that - no alarm.

I don't think I'd want an alarm with SIP devices.  If you had a bunch of SIP softphones, every time someone turned off his laptop you'd go into alarm.

I could see the alarm when some analog lines went out of service (via ASU II) but don't ever remember to see the alarm for IP phones.

Regarding the raising alarm for SIP phones, I believe there we have the treholds to decide whether or not to raise the alarm?

Alarms are not raised for IP sets, they do not count as "lines" for the purpose of alarming. To my knowledge there is no way to raise an alarm is say 20% of IP sets of any kind are off-line.
