Abstract

When a Session Initiation Protocol (SIP) user agent starts up, it registers to the network and initiates numerous subscriptions in order to learn about various network events. This results in a chatty startup procedure which substantially impacts recovery times under avalanche restart. This specification proposes a mechanism whereby the subscriptions can be established as a side effect of the registration, alleviating this problem.
