fix codec mapping for GSM-HR The cfg bits are for AMR-HR, not GSM-HR. The function gsm0808_enc_speech_codec_list2() will return -EINVAL when it encounters GSM-HR with non-zero cfg bits. It appears this mapping was never used before, and my testing of call re-assignment to match MT's codecs (it allows more than just the assigned codec, because it can re-assign) has uncovered this bug via MSC_Tests.TC_ho_inter_msc_out. I don't fully understand all the details why we didn't see this before; anyway, the fix is obvious. Change-Id: I19cff847a0f618ad000d12c1df54c55ef2f79699
This repository contains a C-language implementation of a GSM Mobile Switching Centre (MSC) for 2G (GSM) and 3G (UMTS). It is part of the Osmocom Open Source Mobile Communications project.

OsmoMSC originated from the OsmoNITB project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OsmoNITB 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.
OsmoMSC was one of the parts split off from the old openbsc.git.
