Hello,
Is there a way in openBSC to know if a certain phone that previously connected to my BTS is still connected at a given time ?

In OpenBSC not really, the subscription status is typically in the MSC and/or HLR; so if you're using OsmoNITB you can query the subscriber's LAC on the VTY, or use the CTRL command 'subscriber-list-active-v1'.
If you're using OpenBSC alone, there's no way AFAIK. It only sees a subscriber when it is actually actively sending/receiving right at this moment.

I am using OsmoNITB. Does the command ’subscriber-list-active-v1’ list the phones that are currently connected or should they be active (for example during a call) ?

You can use the location update timestamp in the HLR. The MS will RACH periodically based on the value of the T3212 timer. This is configurable to multiples of 6 minutes with 6 being the minimum. If a phone hasn't updates it's location after that interval has passed you can assume it's not connected

I would have referred you to the user manual http://ftp.osmocom.org/docs/latest/osmonitb-usermanual.pdf but must notice that it isn't very helpful in describing this CTRL cmd.
It returns subscribers that are attached, i.e. no active call or such needs to be going on to be listed.
Might also include a subscriber slightly too soon, see http://osmocom.org/issues/2285
For manual access, using the vty 'show subscriber imsi 12345654321' might be easier (a LAC=0 means not attached).
