[Asterisk-Users] SIP Issues, debug attached

[Eric Wieling]

Thanks.  I figured it was harmless (and seems to be harmless),
but I thought I'd report it anyway.

HOWEVER, even though we are sending a notification to the DTA310
that there are messages waiting, the message waiting light on
the DTA310 doesn't light up.  I don't really care since I get my
message notifications via e-mail, but I did want to mention it.
