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@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:

Can you please provide a complete SIP trace including a working subscription? The SUBSCRIBE you have in the issue report actually seems to have all the details for a resubscription, not a fresh subscription. Since chan_sip doesn't know anything about the subscription to begin with it says it does not exist.

jrgutier: Can you please attach the needed SIP trace? thanks.

I figured it out. You need to 1) create a sip account and 2) you need a username= in that sip entry.
