<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This seems like an odd default behavior. I would suspect that by default we would actually magic up a From URI of our own based instead of telling the server that the message is coming from itself.
Doing this when no to_uri is provided makes good sense though.</pre>

In the case of PUBLISH you are publishing information about yourself usually. It makes sense that it should be coming from you.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm, now I'm a bit confused about terminology being used. Who is the "server" in the server_uri? The XML docs say "SIP URI of the server and entity to publish to" . So in other words, it's the URI of the destination of the PUBLISH request. So let's say the Asterisk server that sends the PUBLISH is Alice, and the Asterisk server that receives the PUBLISH is Bob. You set server_uri=bob@example.com and do not set a from_uri or to_uri. Our SIP request would look something like:
PUBLISH sip:bob@example.com
To: sip:bob@example.com
From: sip:bob@example.com;tag=blahblahblah
That's what's intended? Alice is publishing information about Alice, not Bob. If the From header is supposed to indicate the source of the publication, I'd expect that the From would give some indication that the publication is from Alice.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The name of the entity you are publishing to is generally yourself. I am Alice and I am publishing the state of Alice. This is speaking from a SIP perspective. You'd use server_uri=sip:alice@example.com. This only differs if you are publishing to an entity which is different than your own. I am Alice but I'm publishing the state of Bob.
server_uri=sip:bob@example.com
from_uri=sip:alice@example.com</pre>

It's not the URI of the UAS that is to receive the PUBLISH request. If that's the case, then is the to_uri used to populate the RURI of the PUBLISH request?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It just controls the To URI.
server_uri = Target URI (including user for request URI and the location of where to send it)
to_uri = URI in To header
from_uri = URI in From header</pre>

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.
The res_pjsip_publish_asterisk module implements inbound and outbound support for an 'asterisk' event type. 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.
A wiki page is available at https://wiki.asterisk.org/wiki/display/~jcolp/Exchanging+Device+and+Mailbox+State+Using+PJSIP which has some configuration details with some examples. This should also be reviewed.</pre>
