( https://gerrit.osmocom.org/c/osmo-mgw/+/27391 ) Change subject: Revert "mgcp_codec: do not differentiate between oa and bwe when comparing codec" ...................................................................... Revert "mgcp_codec: do not differentiate between oa and bwe when comparing codec" This reverts commit e0058b7207e022b698aea10f96cc7c0b1209058a. The reason for this revert is that the solution in the reverted patch does not cover a situation where the other side announces both payload formats at the same time. It could be that the end facing to a transit network announces both formats under two different payload types. In this case no conversion would be necessary. Depending on the input format the output would be send to the transit network under the payload type that matches and no conversion would happen at all. This revert re-intruduces the problem that was fixed in the patch before. Therefore it must be merged together with the follow up patch (Ifbd201a2749009a4644a29bd77e1d0fc0c124a9d) that contains the proper fix.
