[Asterisk-Users] Message waiting light not coming on

[Rana Dutt]

I cannot get the Message Waiting Light (MWL) on my Grandstream phone to turn
on when I leave a new voice mail message for that phone. I have specified
the correct mailbox in my sip.conf as follows:

[200]
type=friend
username=200
host=dynamic
context=dialout
callerid=200
dtmfmode=rfc2833
mailbox=200

I also have an IpDialog Siptone II phone, and can't get the MWL to work on
that either.

Did anyone have a problem like this?
