RE: Asterisk Voicemail schema

[andrew <andrew_nh@xxxxxxxxx>]

I have also had problem with xPL messages exceeding
the 1500 byte limit. I think it is counter to the
simple nature of xPL to invent a fragmentation scheme.
Instead I have tried to make my messages simpler so
they are under 1500 bytes. I think for the vm schema I
will limit the info to the last 10 messages. This
should keep the xPL message small

I agree that the web interface for Asterisk is clunky.
The URL embedded in the vm messages is used to
retrieve wav files directly from Asterisk. I have a
small app that runs on my desktop. It lists the
messages that are waiting and allows me to play them
locally. It gets the messages from Asterisk using
http.
