Do you mean you're sending an AMR mode in RTP which is not part of the active set of AMR modes as permitted for the given logical channel?</p> OsmoBTS - Bug #3746: Sending RTP stream with unconfigured AMR mode crashes OShttps://osmocom.org/issues/3746?journal_id=143382019-05-08T18:53:30Zpespin

<p>Yes, that's what i remember observing, however, you're right, I can't reproduce it now, and neither can I reproduce it by sending BE mode AMR to the bts. - That would make sense, given that <a class="external" href="https://gerrit.osmocom.org/#/c/osmo-bts/+/6351/">https://gerrit.osmocom.org/#/c/osmo-bts/+/6351/</a> has been merged for a while now.</p>
<p>As I have been running so many versions of osmo-bts on different hardware over the last 4 months, and I neglected to include info here on which version, I would just go ahead and close this ticket.</p>
<p>I suspect what I refer to was happening with a rather old osmo-bts but I wouldn't really see the point in going back now to verify if it was actually an AMR mode or BE as <a class="user active" href="https://osmocom.org/users/30187">pespin</a> says.</p>
<p>I do have a memory of having seen "AMR CMI X not part of AMR MR set" before this crash, but I didn't log it here so let's just close this.</p>
<p>thanks!</p>
