In the SIP channel, there's a list of active SIP dialogs, which includes all of these when they are active. "sip show channels" in the CLI will show most of these, excluding subscriptions which are shown by "sip show subscriptions"
sipsock_read sends the packet to handle_incoming(), that parses a bit more. If it is a response to an outbound request, the packet is sent to handle_response(). If it is a request, handle_incoming() sends it to one of a list of functions depending on the request type - INVITE, OPTIONS, REFER, BYE, CANCEL etc sipsock_read locks the ast_channel if it exists (an active call) and unlocks it after we have processed the SIP message.
A new INVITE is sent to handle_request_invite(), that will end up starting a new channel in the PBX, the new channel after that executing in a separate channel thread. This is an incoming "call". When the call is answered, either by a bridged channel or the PBX itself the sip_answer() function is called.
The actual media - Video or Audio - is mostly handled by the RTP subsystem in rtp.c

Handle incoming INVITE request.
This is a spiral. What we need to do is to just change the outgoing INVITE so that it now routes to the new Request URI. Since we created the INVITE ourselves that should be all we need to do.

bare-bones support for SIP UPDATE
XXX This is not even close to being RFC 3311-compliant. We don't advertise that we support the UPDATE method, so no one should ever try sending us an UPDATE anyway. However, Asterisk can send an UPDATE to change connected line information, so we need to be prepared to handle this. The way we distinguish such an UPDATE is through the X-Asterisk-rpid-update header.
Actually updating the media session may be some future work.

Imitation TCP reception loop.
This imitates the logic used by SIP's TCP code. Its purpose is to either 1) Combine fragments into a single message 2) Break up combined messages into single messages
| fragments | The message fragments. This simulates the data received on a TCP socket. | |
| num_fragments | This indicates the number of fragments to receive | |
| overflow | This is a place to stash extra data if more than one message is received in a single fragment | |
| [out] | messages | The parsed messages are placed in this array |
| [out] | num_messages | The number of messages that were parsed |
| test | Used for printing messages |

parse the Allow header to see what methods the endpoint we are communicating with allows.
We parse the allow header on incoming Registrations and save the result to the SIP peer that is registering. When the registration expires, we clear what we know about the peer's allowed methods. When the peer re-registers, we once again parse to see if the list of allowed methods has changed.
For peers that do not register, we parse the first message we receive during a call to see what is allowed, and save the information for the duration of the call.

Handle 422 response to INVITE with session-timer requested.
Session-Timers: An INVITE originated by Asterisk that asks for session-timers support from the UAS can result into a 422 response. This is how a UAS or an intermediary proxy server tells Asterisk that the session refresh interval offered by Asterisk is too low for them. The proc_422_rsp() function handles a 422 response. It extracts the Min-SE header that comes back in 422 and sends a new INVITE accordingly.

Process the Via header according to RFC 3261 section 18.2.2.

This function will update the destination of the response according to the Via header in the request and RFC 3261 section 18.2.2. We do not have a transport layer so we ignore certain values like the 'received' param (we set the destination address to the address the request came from in the respprep() function).

Part of PBX channel interface.
If we have qualify on and the device is not reachable, regardless of registration state we return AST_DEVICE_UNAVAILABLE
For peers with call limit:
For peers without call limit:
Peers that does not have a known call and can't be reached by OPTIONS
If we return AST_DEVICE_UNKNOWN, the device state engine will try to find out a state by walking the channel list.
The queue system (app_queue.c) treats a member as "active" if devicestate is != AST_DEVICE_UNAVAILBALE && != AST_DEVICE_INVALID
When placing a call to the queue member, queue system sets a member to busy if != AST_DEVICE_NOT_INUSE and != AST_DEVICE_UNKNOWN

Makes sure that body is properly formatted PIDF.
Specifically, we check that the document has a "presence" element at the root and that within that, there is at least one "tuple" element that contains a "status" element.
XXX This function currently assumes a default namespace is used. Of course if you're not using a default namespace, you're probably a stupid jerk anyway.
| req | The SIP request to check | |
| [out] | pidf_doc | The validated PIDF doc. |

Terminate the uri at the first ';' or space. Technically we should ignore escaped space per RFC3261 (19.1.1 etc) but don't do it for the time being. Remember the uri format is: (User-parameters was added after RFC 3261)
* * sip:user:password;user-parameters@host:port;uri-parameters?headers * sips:user:password;user-parameters@host:port;uri-parameters?headers * *

update_call_counter: Handle call_limit for SIP devices Setting a call-limit will cause calls above the limit not to be accepted.
Remember that for a type=friend, there's one limit for the user and another for the peer, not a combined call limit. This will cause unexpected behaviour in subscriptions, since a "friend" is two devices in Asterisk, not one.
Thought: For realtime, we should probably update storage with inuse counter...

We use libxml2 in order to parse XML that may appear in the body of a SIP message. Currently, the only usage is for parsing PIDF bodies of incoming PUBLISH requests in the call-completion event package. This variable is set at module load time and may be checked at runtime to determine if XML parsing support was found.

Here we implement the container for dialogs (sip_pvt), defining generic wrapper functions to ease the transition from the current implementation (a single linked list) to a different container. In addition to a reference to the container, we need functions to lock/unlock the container and individual items, and functions to add/remove references to the individual items.

Main socket for UDP SIP communication.
sipsock is shared between the SIP manager thread (which handles reload requests), the udp io handler (sipsock_read()) and the user routines that issue udp writes (using __sip_xmit()). The socket is -1 only when opening fails (this is a permanent condition), or when we are handling a reload() that changes its address (this is a transient situation during which we might have a harmless race, see below). Because the conditions for the race to be possible are extremely rare, we don't want to pay the cost of locking on every I/O. Rather, we remember that when the race may occur, communication is bound to fail anyways, so we just live with this event and let the protocol handle this above us.
