Addition:

The problem *only* happens if at the same time a third (outgoing) call
is initiated (via ring group) - which is *not answered* but closed at
the moment the call is accepted internally.

If the third (-> outgoing) call via ring group is omitted, things work
as expected.

Calls in detail:

outgoing call:    extension -> asterisk -> provider
incoming call:     provider -> asterisk -> extension
outgoing call* via ring group: asterisk -> provider -> ext. destination

answer the incoming call
outgoing call* is exited.


* triggered by incoming call
