Enforce Offer Answer Model
Determines whether or not the unit requires strict adherence
to RFC 3264 when receiving an answer from the peer when
negotiating capabilities for the establishment of a media
session.
When enabled, the following guidelines from the Offer-Answer
Model must be strictly followed. An answer must:
* Include at least one codec from the list that the unit
sent in the offer;
* Contain the same number of media lines that the unit put
in its offer.
Otherwise, the answer is rejected and the unit ends the call.
When disabled, then the peer can freely:
* Send back a brand new list of codecs;
* Add new media lines.
As long as at least one codec sent back was present in the
initial offer, the call can go on. Any media line added by the
peer is simply ignored.
The InteropAllowLessMediaInResponse parameter allows other
deviations from the Offer/Answer model.
