laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-msc/+/19213 ) Change subject: Clear Command: set cause value to "Call Control" ...................................................................... Clear Command: set cause value to "Call Control" So far, by failing to initialize the cause value, we always send a Clear Command cause == 0, which actually means "Radio Interface Message Failure". This is seen in all my logged network traces of osmo-msc lab testing. "Call Control" seems to be the only cause value that remotely fits a normal release procedure, even if it was not voice call related, see 3GPP TS 48.008 3.2.1.21.
