OpenBSC and Half Rate support on ip.access.

[./Vervelak]

Hello List

I'm trying to make my openbsc installation work in half rate mode but
I'm facing some errors.
I'm wondering if someone could provide me with more info or help me to
configure openbsc.
I have changed in openbsc.cfg the timeslots 2 to 7 from 
phys_chan_config TCH/F into  phys_chan_config TCH/H also I have tested
changing neci bit and change audio codecs but no luck.
Am I missed something? Is there any way to run osmo-nitb with gsmtap?
openbsc.cfg is attached

Thanks in advance.
