To Do

• Move conf option tag text from cc-conferencing to a SIP document

• Finalize split of conference package

• Finalize split with URI list documents– Conference Factory URI definition/flows will

move from cc-conferencing to a new SIPPING draft which includes INVITE URI list draft.

• Then, all four documents ready for WGLC
