https://gerrit.osmocom.org/c/osmo-bts/+/32100/comment/9afb9be6_39e72558 PS2, Line 16: The case of TCH/H is still unhandled, and it may or may not be : possible to handle correctly, particularly for rtp always-output mode. : The fundamental difficulty is that in order to produce truly : undisrupted RTP timing, two BFI packets will need to be sent for : one FACCH, spaced 20 ms apart - but if the PHY only sends one : GsmL1_Sapi_FacchH message surrounded by a 40 ms time gap, then : we may be out of luck. * might make sense to add this as a comment into/above the if-clause that treats FACCH/F but not FACCH/H * in FACCH/H you could still send that second RTP packet, but with a high jitter?
