[asterisk-users] pstn hangs up: MWI no message waiting ??

[sean darcy]

pstn incoming on a TDM400P, sometimes i* won't answer, going into
a loop like this:

  -- Starting simple switch on 'DAHDI/4-1'
[Jan 16 10:38:55] NOTICE[5808]: chan_dahdi.c:7130 ss_thread: Got event 
18 (Ring Begin)...
[Jan 16 10:38:57] NOTICE[5808]: chan_dahdi.c:7130 ss_thread: Got event 2 
(Ring/Answered)...
[Jan 16 10:38:57] NOTICE[5808]: chan_dahdi.c:7299 ss_thread: MWI: 
Channel 4 no message waiting!
     -- Hungup 'DAHDI/4-1'
........................

I don't have any Message Waiting set ( or at least I don't think so.)

Restarting * solves it for a while.

Any suggestions?
