Rodion,

Great that you've got GPRS, calls and SMS working!

There is no single recommended configuration, it all depends on your
requirements. Master version of OpenBSC support dynamic switching
between TCH and PDCH, but I personally have not tested this yet. Just
be aware that TCH/F is currently not working in dynamic configurations
- only TCH/H does. I suggest you write to OpenBSC mailing list, as
it's a better place for this type of a question.

PS Please don't remove mailing list from CC.
