Hacky way to make HTML voicemail notifications work

Quite simply, if you want HTML voicemail email notifications to work you have to define the content type to be text/html. Here’s what I came up with that’s a super simple hack, but it works and allows me to send HTML voicemail notifications.

Create the file in /usr/local/bin/htmlsendmail and put the following in it:

NEWVAL=$(sed 's/Content-Type: text\/plain/Content-Type: text\/html/g' <<< "$VALUE")
echo "$NEWVAL" | /usr/sbin/sendmail -t -v

Make it executable:

chmod +x /usr/local/bin/htmlsendmail

Now in Settings >> Voicemail Admin >> Settings >> Email Config set the Mail Command option to be /usr/local/bin/htmlsendmail

Here’s an HTML template you can try out:

There is a new voicemail in mailbox ${VM_MAILBOX}:</p>
    <th align="left">From (NAME):</th>
    <th align="left">From (Number):</td>
    <td><a href="tel://${VM_CIDNUM}">${VM_CIDNUM}</a></td>
    <th align="left">Length:</td>
    <td>${VM_DUR} seconds</td>
    <th align="left">Date:</td>
<p>Dial *98 to access your voicemail by phone.<br>

Have fun!
