Using 1.6.1-169788, now it just never answers:

     -- Starting simple switch on 'DAHDI/4-1'
[Jan 22 15:33:01] NOTICE[28000]: chan_dahdi.c:7144 ss_thread: Got event 
18 (Ring Begin)...
[Jan 22 15:33:04] NOTICE[28000]: chan_dahdi.c:7144 ss_thread: Got event 
2 (Ring/Answered)...
[Jan 22 15:33:04] NOTICE[28000]: chan_dahdi.c:7316 ss_thread: MWI: 
Channel 4 no message waiting!

and that's it.

Started bug 14313.
