Summary:                    Subscriptions to hints on another server only allows
1 watcher at a time
Description: 
My company off-loaded the parking lot to another server to help debug a
segfault with parking (bugs.digium.com/view.php?id=14440).

I'm trying to setup BLF with the parameter 99924700 at 172.16.16.3, and it
works fine for the first user. I've set it up the following so it will
allow me to subscribe without having a sip entry on the box:
autocreatepeer=yes
insecure=very

When the next person tries SIP SUBSCRIBE, it doesn't add to the list. It
overwrites the other one without any notification, which is evident when I
turn off the first client and it gives this SIP response:
