=== Description ===

A Resource List Server (RLS) services application is a Session Initiation Protocol (SIP) application whereby a server receives SUBSCRIBE requests for a resource, and generates subscriptions towards a resource list. The received NOTIFY messages are the  aggregated downstream to the original subscriber generating less traffic to the subscriber end-user device.

This script implements sending SUBSCRIBE to a RLS server and receiving NOTIFY messages from it.

Usage: sip_subscribe_rls [options] [target-user@target-domain.com]

This script will SUBSCRIBE to the presence event published by the specified

SIP target assuming it is a resource list handled by a RLS server. The RLS

server will then SUBSCRIBE in behalf of the account, collect NOTIFYs with the

presence information of the recipients and provide periodically aggregated

NOTIFYs back to the subscriber. If a target address is not specified, it will

subscribe to the account's own address. It will then interprete PIDF bodies

contained in NOTIFYs and display their meaning. 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

                        Corresponds to section Account_NAME in the

                        configuration file. If not supplied, the section

                        Account will be read.

  --sip-address=SIP_ADDRESS

                        SIP address of the user in the form user@domain

                        Password to use to authenticate the local account.

                        This overrides the setting from the config file.

                        Display name to use for the local account. This

  -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.

  -c CONTENT_TYPE, --content-type=CONTENT_TYPE

                        for this subscription. For the known events this does

                        not need to be specified, but may be overridden".
