( https://gerrit.osmocom.org/c/osmo-mgw/+/34566?usp=email ) Change subject: mgw: Configure IuUP if codec set during MDCX ...................................................................... mgw: Configure IuUP if codec set during MDCX The mgcp client may first configure the connection to use RTP-AMR, but after setting up another call leg may find out that both legs are IuUP and hence want to forward the IuUP between the 2 connections instead. In that case, an MDCX with codec VND.3GPP.IUFP would be set. Until now, osmo-mgw didn't take that scenario into account, and it was only upgrading the rtp conn to iuup internally during CRCX. As a result, in the mentioned scenario osmo-mgw would continue to output RTP instead of IuUP after the MDCX with VND.3GPP.IUFP, which is wrong.
