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.
adigeo@ag-imac3:~$sip-subscribe-rls -h Usage: sip-subscribe-rls [options] [email@example.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 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 SIP address of the user in the form user@domain -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. -c CONTENT_TYPE, --content-type=CONTENT_TYPE "Content-Type" the UA expects to receving in a NOTIFY for this subscription. For the known events this does not need to be specified, but may be overridden". -s, --trace-sip Dump the raw contents of incoming and outgoing SIP messages (disabled by default). -l, --log-pjsip Print PJSIP logging output (disabled by default).
