Trying it over our network (openbsc only with TCH/H
timeslots and hr default codecs ) we saw that handsets are still trying TCH/F, is TCH/H
supported by bb???
Yes, I've tested that with a MS tester a while ago.
Make sure you also have:
channel-capability sdcch+tchf+tchh
in the config.
It is _not_ supported by the nanoBTS though.
