SA4 is definitely the option, but they are focused, again, on LTE only,
around EVRC family, so they has a differetnt roots and different agendas
from IETF now.

It would also be hard to 'object' to transport work being done in
traditional 'codec shops' (such as the ITU and MPEG) if this goes ahead.

A quality codec standard is usually backed by
* testing
* conformance files
* reference software

and a fairly rigorous design process.  When SMPTE took on VC-1 from
Microsoft, I think both they and Microsoft were surprised by the amount
of work involved.

FWIW, 3GPP SA4 is also a place with interest in codecs for packet
networks, and has standardized codecs in the past.  Opening a new work
item there is not trivial, but can be done.
