And what if the call does not go through a TDM card? And ore
importantly: how can you tell who is the caller and who is the callee?
The rtp-tap interface basically tells you that channel X had a call at
time Y.

If you control recording through the monitoring interface of Asterisk
you can start and stop the recording when you need it. You can also
provide better information aobut the call. But again, it means that this
is part of Asterisk, and I figure Sangoma has quite a few non-Asterisk
customers.

My message was an explicit call for testers, if you haven't noticed :-)

I snip content that is not relevant to my reply. Whoever reads this list
already read about the Sangoma interface previously. I had nothing to
say about it. It was not related to that new branch.
