!{}http://www.openxcap.org/chrome/site/SIMPLE-Winfo.png!

Watchers are defined as entities that request (i.e., subscribe to)

information about a resource, using the SIP event framework, RFC 3265. There

is fairly complex state associated with these subscriptions.  This state

includes the identity of the subscriber, the state of the subscription, and 

so on. The union of the state for all subscriptions to a particular resource

is called the watcher information for that resource.  This state is dynamic,

changing as subscribers come and go.  As a result, it is possible, and

indeed useful, to subscribe to the watcher information for a particular

resource. An important application of this is the ability for a user to find

out the set of subscribers to their presentity. This would allow the user to

provide an authorization decision for the subscription.

This script implements SUBSCRIBE for the watcher info event package and

manipulation of the pres-rules document that holds the presence policy of

the subscribing user.

adigeo@ag-imac3:~$sip-subscribe-winfo -h

Usage: sip-subscribe-winfo [options] [target-user@target-domain.com]

This script displays the current presence rules, SUBSCRIBEs to the

presence.winfo event of itself and prompts the user to update the presence

rules document when a new watcher is in 'pending'/'waiting' state. The program

will un-SUBSCRIBE and quit when CTRL+D is pressed.

Options:

  -h, --help            show this help message and exit

  -a ACCOUNT_NAME, --account-name=ACCOUNT_NAME

                        The name of the account to use.

  -s, --trace-sip       Dump the raw contents of incoming and outgoing SIP

                        messages (disabled by default).

  -j, --trace-pjsip     Print PJSIP logging output (disabled by default).
