You would be better off asking this questions in asterisk-r2 mailing list.

I will answer the same way that I answered back then. You need to enable
protocol debugging. Without protocol debugging there is no way to tell what
is happening to the call.

Read the sample chan_dahdi.conf included with Asterisk and search for mfcr2
logging options.

Having said that, it is possible in international calls you need to specify
a different caller category.
