gsm_data: subslots_per_pchan_vamos[GSM_PCHAN_TCH_F]: 2 -> 1
As far as I can see, multiplexing one TCH/F and two TCH/H sub-slots on one timeslot is not properly implemented yet. At least when trying to 'activate-all-lchan' from the VTY, I see messages like:
DCHAN ERROR lchan(0-1-2-TCH_F-shadow1)[0x612000012220]{WAIT_ACTIV_ACK}: (type=TCH_F) Error encoding Channel Number: pchan TCH/F ts 2 ss 1 (VAMOS shadow)
The logic basically tries to activate the second shadow sub-slot of TCH/F (not TCH/H!), which indeed does not exist.
