in mgcp_codec.c we have a function mgcp_codec_pt_translate that is used to find the equivalent payload type number on an opposite connection. This is quite specific and the resulting payload type number may still belong to a codec that might require some form of conversion. Lets refactor this so that the function just finds a convertible codec for a given connection. This also opens up other usecases. The payload type conversion like we did it before can then be done with a few lines in mgcp_network.c Related: OS#5461 Change-Id: I085260a2ca8cfecdb58656b7a046c536189e238d |

About OsmoMGW ============= OsmoMGW originated from the OpenBSC project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks. OsmoMGW was one of the parts split off from the old openbsc.git. It originated as a solution to merely navigate RTP streams through a NAT, but has since matured to a Media Gateway implementation that is capable of streaming RTP for 2G (AoIP) and 3G (IuCS) GSM networks as well as (still not implemented at time of writing) transcoding between TRAU, various RTP payloads and IuUP. The OsmoMGW program exposes an MGCP interface towards clients like OsmoMSC and OsmoBSC, and receives and sends RTP streams as configured via MGCP. The libosmo-mgcp-client library exposes utilities used by e.g. OsmoMSC (found in osmo-msc.git) to instruct OsmoMGW via its MGCP service.
