Neels Hofmeyr nhofmeyr at sysmocom.de> I'm trying to work out using half rate channel in my testbed setup but unfortunately, I'm getting an error message Originate Failed. Cause: INCOMPATIBLE_DESTINATION. Do I need to adjust some configurations in OSMO to make it work? Codec negotiation is quite broken in OsmoMSC. Patches to fix that are tested and have been almost-ready for years now, unfortunately there was not sufficient human resource available to fully finish and merge them. To use proper codec negotiation from MS thru SIP, you may try using: osmo-msc branch neels/mncc_codecs3 osmo-sip-connector branch neels/codecs3 (The last actually tested versions were neels/mncc_codecs2 and neels/codecs2, I just now rebased those onto current master and resolved some conflicts, however don't have the time to also test them. So if 3 fails, you may also try 2.) Without above patches, the codec in osmo-sip-connector is actually hard coded and you will be able to use only that single codec, chosen by actually patching the source code of osmo-sip-connector. *With* above patches, a) codec selection is based on more information in osmo-msc, and b) the codec is properly transported through to the SDP that ends up in the SIP and back from SIP to the MSC. Feedback would be appreciated! If these patches help you, then it confirms (again) that someone should fund us to work on merging them... Thanks! ~N
