Abstract

Call Park and Call Retrieve are useful telephony services that are familiar to many users. Existing implementations using the Session Initiation Protocol (SIP) show that a variety of approaches can be taken, with varying degrees of interoperability. This draft discusses a number of feature variations, and how they may be implemented using existing techniques. An additional URI parameter is also described, which enables further common use-cases to be implemented.
