String fields aren't exactly the same. String fields can have some extra space, unless I calculate and determine the exact amount of space ahead of time.... I suppose. This pattern is used elsewhere, though.

> The res_pjsip_outbound_publish module is a common module which provides basic logic for setting up outbound PUBLISH clients, handling authentication requests, handling configuration, and lifetime. Extra modules implement specific event types which are registered with res_pjsip_outbound_publish. Since it takes care of configuration when an outbound PUBLISH is configured extra configuration can be passed to the event type implementation to further configure itself.

This event type conveys device and mailbox state between Asterisk instances using a JSON content body. As internal device or mailbox state changes the module sends a PUBLISH message to other configured instances. When a PUBLISH is received the contents are examined and a device or mailbox state change queued up within Asterisk. To restrict what is sent and received filtering is available using regular expressions which can reduce SIP traffic.
