<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;">The handling of phoneprov_cfg is incorrect. When ast_config_load() returns you have to check for the special pointer values:
#define CONFIG_STATUS_FILEUNCHANGED (void *)-1
#define CONFIG_STATUS_FILEINVALID (void *)-2
before you can treat phoneprov_cfg as a normal pointer that ast_config_destroy() can handle.
Passing those special pointers to ast_config_destroy() will cause a crash.</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;">The big piece missing for me to finally transition to pjsip was the ability to mirror the auto provisioning features of res_phoneprov. The first step (this patch) is to make res_phoneprov more modular so other modules (like pjsip) can provide configuration information instead of res_phoneprov relying solely on users.conf and sip.conf. To accomplish this a new ast_phoneprov public API is now exposed which allows config providers to register themselves, set defaults (server profile, etc) and add user extensions.
ast_phoneprov_provider_register registers the provider and provides callbacks for loading default settings and loading users.
ast_phoneprov_provider_unregister clears the defaults and users.
ast_phoneprov_add_extension should be called once for each user/extension by the provider's load_users callback to add them.
ast_phoneprov_delete_extension deletes one extension.
ast_phoneprov_delete_extensions deletes all extensions for the provider.
res_phoneprov actually registers itself as the provider for sip/users and is always available and is the default.
Writing a new provider...
Since res_phoneprov is also it's own provider, examples of what a new provider would have to do are in load_users() in res_phoneprov.c. Those functions gather the information from users.conf and sip.conf and call the ast_provider_register and ast_phoneprov_add_extension apis.
So...
The provider creates a callback function which calls the ast_phoneprov_add_extension api for each user.
It then calls ast_phoneprov_provider_register with the callback.
res_phoneprov then calls the callback to cause the actual load.
During normal http server ops, all work is done by res_phoneprov and the provider is never called again unless a reload is needed.
If the provider wants to reload it can simply unregister and reregister or it can call its own load_users callback.
If res_phoneprov wants to reload, it iterates over its registry and calls the providers callback.
NOTE: If res_phoneprov is actually unloaded, it has no way to know what providers were registered (other than itself) so a subsequent load will have nothing but it's own users.
Additional changes...
I added a few convenience functions to chanvars for creating lists and finding and deleting entries. No existing code was touched.
Next steps...
A provider for res_pjsip.

I actually use it with Grandstream phones and everything worked exactly as expected.
