Hello,
Using kazoo only to connect to amqp gives an error if the db_url is not specified. If db_url is specified it tries to do presence related stuff even if not intended. The solution was to use:
modparam("kazoo", "pua_mode", 0) which I found here:
http://lists.sip-router.org/pipermail/sr-users/2015-September/090092.html

This is not documented in the kazoo module. Would be great if this is added in the module documentation to simplify the use of module.

Thanks,

- Jayesh
