Call: Support SDP Capability Negotiation (RFC 5939)

Description
Look at how to support SDEP Cap Neg..
It is required by TS 126.114 section 6.2.1a (LTE SIP/RTP requirements) to use a profile other than RTP/AVP, so we must make sure that our API supports it.
The big thing about SDPCapNeg is that you can offer more than one possible configuration at the same time.
There are three ways we can support this:
- Modify the MediaDescriptionOffer to include multiple offers at the same time
- Have the CM do each offer in order until one is accepted by the client
- Completely move the negotation inside the CM and make the API more simple by only having the client declare all of its capabilities and then have the CM just tell the client about the chosen offer.
