Really, RAII_VAR isn't terribly useful here. You have a single off nominal return path, and since you have to manipulate the reference count prior to pjsip_sip_endpt_send_request, you have to decrement the reference there anyway.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There's a number of assumptions being made here about the allowed size of users/domains that I'm not sure are guaranteed to always be true. The same is also true for the size of the two concatanated together - in fact, AST_UUID_STR_LEN is a poor choice here, as it is defined to be substantially smaller than both:
#define AST_UUID_STR_LEN (36 + 1)
I'd suggest duplicating the username/domain on the stack, calculating the length of both, then creating the ID from the actual length of the user/domain.</pre>

I'd also get rid of the RAII_VAR, since it is only needed if a domain_alias has been defined.
if ((alias = ast_sorcery_by_id(...)) {
// construct ID with alias
ao2_ref(alias, -1);
} else {
// construct ID normal way
}</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Because this is using an ao2_callback to get the contact, it's going to be rather expensive. If we were searching based on the contact's typical hash key this wouldn't be a problem - but here, this is an O(n) search.
I'm not sure how we typically use the contacts on an AOR, but if we're iterating over the container a lot, an ao2 container may not be the best choice of storage. ao2 containers with linear searches perform much worse than the linkedlist macros.
Also: why OBJ_UNLINK? Why would you want to remove the contact from the AOR when all you're trying to get is the Path header?</pre>

You could also reduce indentation by inverting the logic on this statement and bailing early if this is not a REGISTER_METHOD or not successful.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This adds Path support to chan_pjsip in res_pjsip_path.c with minimal additions in res_pjsip_registrar.c to store the path and additions in res_pjsip_outbound_registration.c to enable advertisement of path support to registrars and intervening proxies.
Path information is stored on contacts and is enabled via Address of Record (AoRs) and Registration configuration sections.
While adding path support, it became necessary to be able to add SIP supplements that handled messages outside of sessions, so a framework for handling these types of hooks was added in parallel to the already-existing session supplements and several senders of out-of-dialog requests were refactored as a result.</pre>
