@seandarcy: I don't know about the dropped calls, but the "Unrecognized Garbage" I believe will be resolved for you if you upgrade your dahdi_tools.

It was accounted for here in commit r9066 which is in 2.4.0 and later releases.

@seandarcy: Also, looking at issue DAHLIN-230, it appears that you do not get the dropped calls when you run DAHDI-linux trunk?

Suspended due to no response from reporter, and sruffell's comment about this likely being already resolved.
