Hi,

I have  issue about device  registration failed frequently  (8 to 10  times  in hours).  I getting this error logs  in rabbit and  kamailio log.

1. I have configured 3 kazoo node as   a1.sip.pescoe.com, a2.sip.pescoe.com, a2.sip.pescoe.com,  on same host installed kamailio.

2. one separate rabbit node 

3. three freeswitch node.
