- Assignee set to msuraev
- make the setting VTY-configurable and then set the respective bits in OML/RSL messages.
- make sure to process measurement reports correctly, i.e. if DTXu is active, only use the -SUB values of the measurements should be used for handover decisions, as the -FULL measurement reports contain the muted bursts/blocks.
- make sure the voice frame handlign works for all codecs (HR/FR/EFR/AMR-HR/AMR-FR) and in the followign modes:
- internal MNCC handler without RTP proxy (RTP direct between BTSs)
- internal MNCC handler with RTP proxy (RTP via NITB)
- external MNCC handler (like lcr, osmo-sip-connector) with TCH data via MNCC
- external MNCC handler (like lcr, osmo-sip-connector) with RTP directly to lcr/osmo-sip-connector
- perform and end-to-end test with ip.acces nanoBTS
- perform and end-to-end test with osmo-bts

make sure to process measurement reports correctly
DTXu should not affect the value of rxqual transmitted by ms in measurement reports because it's calculated based on downlink signal - the DTXd will. However the values measured by BTS itself will be affected by DTXu and not DTXd.

- got acked RSL "mode modify request" with
DTXd and DTXu bits set in Channel Mode IE - got Measurement Report RSL from BTS with "DTX used" bit set in Measurement Results.
Note: in the same report there is Uplink Measurement IE with DTXd bit unset.

tested all codecs with internal and external mncc handler (osmo-sip-connector + kamailio), test with external voice source (asterisk) will be made once current rtp issue is fixed.
