<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;">Josh mentioned that variable naming could use some work, so I'm going to chime in with specific places where I agree.
In this case, ast_exten_state sounds very generic and not like something that only applies to SIP. Using something like res_sip_exten_state or just sip_exten_state gives a better indication that this structure is SIP-specific.</pre>

A simple API was developed so that specific extension state providers can attach and create the relevant NOTIFY request body, according to their registered type, for the outgoing request. The framework maintains the list of providers and looks up the appropriate provider upon a state change for an associated registered subscription. For instance, a provider can be registered for a particular event/media type tuple (ex: presence and application/xml+pidf). When a subscription comes in for a given event/media type it is the responsibility of the registered provider to create that NOTIFY body.
Unfortunately pjsip only allows an event and its associated media types to be registered all at once, so providers are not in themselves modules, but in order to maintain some division and to make it easier to move into a module later providers can and should reside in separate files (found in res/res_sip_providers/).
Included in this review is also an implementation of providers for the following types: event=presence; media_type=application/pidf+xml, application/xml+pidf, and application/cpim+pidf+xml.
