1. MIG – MIGration of Communication Services to SIP
A Proposed BoF for IETF67
San Diego

2. Proposed Scope
To insure service interoperability across heterogeneous networks
Evaluate the interoperability of specific services to identify issues, clearly describe the identified service interoperability problems, document requirements for solutions to these issues, and outline the pros / cons of possible approaches to satisfy these requirements.
Where appropriate, Best Current Practices (BCP), new P-headers, or new event packages would be developed to address the requirements identified by this group.
Where changes to the core SIP specification are implied, this will be referred to SIP/SIPPING for development of any new protocol elements described in Change Policy for SIP (RFC 3427).
