I have trx, bts, bsc, msc, stp, hlr, and sip installed...on a Orange PI
Zero.
asterisk runs on a separate machine.. SDR is Ettus B100 for now....
CPU is 4 core arm H2+, idle with stack running 75% idle, increasing to
90% with one call
active, i.e. lots of CPU left. Memory consumption 250 out of 512 M, so
plenty memory left.
In all -- impressive!!
A pocket-size GSM base station.
