sip_subscribe_winfo

To use this script you must to have a valid [wiki:configuration_file configuration file].

=== Description ===

[[Image(http://www.openxcap.org/chrome/site/SIMPLE-Winfo.png, align=right, nolink)]]
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]

This example script will use the specified SIP account to SUBSCRIBE to the
presence.winfo event of itself and request action to be taken 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 NAME, --account-name=NAME
The account name from which to read account settings.
Corresponds to section Account_NAME in the
configuration file. If not supplied, the section
Account will be read.
--sip-address=SIP_ADDRESS

-p PASSWORD, --password=PASSWORD
Password to use to authenticate the local account.
This overrides the setting from the config file.
-n DISPLAY_NAME, --display-name=DISPLAY_NAME
Display name to use for the local account. This
overrides the setting from the config file.
-e EXPIRES, --expires=EXPIRES
"Expires" value to set in SUBSCRIBE. Default is 300
seconds.
-o IP[:PORT], --outbound-proxy=IP[:PORT]
Outbound SIP proxy to use. By default a lookup of the
domain is performed based on SRV and A records. This
overrides the setting from the config file.
-x XCAP_ROOT, --xcap-root=XCAP_ROOT
The XCAP root to use to access the pres-rules document
for authorizing subscriptions to presence.
