dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/32153 ) Change subject: MGCP_Test: support multiple codecs ...................................................................... MGCP_Test: support multiple codecs At the moment The RTP emulation and MGCP_Test only allow to specify one codec and one set of RX/TX fixed payload octet strings to verify against. This is quite limiting since it might be necessary to test against different types and formats of payloads simultaneously in order to see if osmo-mgw converts or forwards them correctly. Let's extend this to support multiple codecs on MGCP/SDP level plus support for multiple RTP payloads on RTP emulation level.
