Sip Subscribe RLS
Updated 2,133 Days AgoPublic

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.

This script is available in the Sip Clients package which must be installed separately from the SIP SIMPLE client SDK package.

Simple RLS Services

adigeo@ag-imac3:~$sip-subscribe-rls -h
Usage: sip-subscribe-rls [options] []

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.
