OK - to partly answer my own question, this looks like it relates to
how the VM notifications for multiple registrations get sent to the
phone. It's basically a case of what the most recent message said. The
notification messages look like this:
First, for the registration with a waiting message:
12 headers, 3 lines
Reliably Transmitting (no NAT) to 172.16.16.102:5060:
NOTIFY sip:[EMAIL PROTECTED]:5060 SIP/2.0
Via: SIP/2.0/UDP 172.16.16.12:5060;branch=z9hG4bK78d78c38;rport
From: "asterisk" <sip:[EMAIL PROTECTED]>;tag=as06287858
To: <sip:[EMAIL PROTECTED]:5060>
Contact: <sip:[EMAIL PROTECTED]>
Call-ID: [EMAIL PROTECTED]
CSeq: 102 NOTIFY
User-Agent: Asterisk PBX
Max-Forwards: 70
Event: message-summary
Content-Type: application/simple-message-summary
Content-Length: 89
Messages-Waiting: yes
Message-Account: sip:[EMAIL PROTECTED]
Voice-Message: 1/0 (0/0)
Then for the registration with no messages:
12 headers, 3 lines
Reliably Transmitting (no NAT) to 172.16.16.102:5060:
NOTIFY sip:[EMAIL PROTECTED]:5060 SIP/2.0
Via: SIP/2.0/UDP 172.16.16.12:5060;branch=z9hG4bK76c73b57;rport
From: "asterisk" <sip:[EMAIL PROTECTED]>;tag=as49fbf0a7
To: <sip:[EMAIL PROTECTED]:5060>
Contact: <sip:[EMAIL PROTECTED]>
Call-ID: [EMAIL PROTECTED]
CSeq: 102 NOTIFY
User-Agent: Asterisk PBX
Max-Forwards: 70
Event: message-summary
Content-Type: application/simple-message-summary
Content-Length: 92
Messages-Waiting: no
Message-Account: sip:[EMAIL PROTECTED]
Voice-Message: 0/0 (0/0)
If this one is the last one received, the MWI goes off until the first
registration expires, when the first NOTIFY is sent again and the MWI
lights up again.
Notice that I have even set the Message-Account to be different in each
case, so that doesn't work either.
Does anyone have any further insight before I log this as a bug?

I remember seeing something like this on the list a while ago, but I'm
darned if I can find it.
We have a number of Polycom IP501 phones, some of which have more than
one registration on them. When a voicemail is left for a phone with
only one registration, the MWI lights up and stays lit until the
voicemail is listened to.
However, on our phones with more than one registration, the MWI goes
out periodically, and then relights a short time later with the
characteristic Polycom warble tone.
Any ideas what could be wrong here? I have a hunch that it has to do
with registration expiry, but I'm not sure.
