Can any one explain where the GSSI is ?
I can se a lot of ISSI called SSI. But haw is this compared to GSSI. Or is SSI some part of GSSI.

currently i don't diffrentiate between the two. the SSI can be either ISSI or GSSI.

some future version will probably do it

differentiate between ISSI's en GISSI's will be very useful to filter en monitor large networks.

GSSI vs ISSI

I have found out haw to see the differens with GSSI and ISSI.
This is method is not working every time. But this is what I have seen most of the time.

When receive first number it is normal the ISSI then comes the GSSI and
the 3. number is the next ISSI.

I will try to show an example.

Blue bar *PLAY*
1010090 ISSI Radio starting Group call
1001001 GSSI Group In use
1010091 ISSI Other Radio answer in Group call

yes this is rights but it will be nice telive make diffrentiate between the two also for in the log file.
So you can see in the log what GISSI are used.

On mines I see for example
104987
19209
105638

I know that 19209 is the service so I set a description for that. So I know I am listening to the service, then the 2 six digit SSIs I set as the call sign for that user so it's

E1 North
Service
Control North

Maybe he wants a complete linux distribution with TElive included as iso, so he can run it out of the box?
Just an idea, I don't unterstand it, too ;-)

 

[grahampaull]

Ahh, now that you mention I think that's what he wants.

Interesting article about vulnerability of tetra system in Slovenia:

Vdor v komunikacijo policije razkril hude varnostne ranljivosti sistema Tetra • Pod

 

[hansheesbeen]

Nice software maybe he wants tot share... Oh no wait.... we have telive !!!!

 

[yt1pro]

Yes, but it wouldn't be bad to have both

 

[grahampaull]

Google translate doesn't do this article any justice... Anyone got a TL;DR for this ?
