actually one channel runs fine on a rpi 3

you could probably do two, and maybe stretch this to three with some audio hickups

Thanks, I've tested on a quite busy network, but it's not too much status traffic. Maybe something every 5-10 minutes on the site I checked.

All status messages so far has been 65024. Also in all cases so far the SSI has been the mobile station id, and the SSI2 a GSSI (group). This was the same on two completely independent systems.

A have also testet on 2 sites on same network and on one site it only give same result 5-10 minutes.
The other site it give 0.

It still could be nice to know what is ISSI and GSSI. I know it is not simple to implement from SSI.
I have try to se what different in the hex dump off SSI but cant se the differen in SSI.
So that have to be done in the osmo core code. I have a system I know what is the GSSI and ISSI.
And that system we can use to check against if this is any help.
