( https://gerrit.osmocom.org/c/osmo-msc/+/28509 ) Change subject: Change CC_CAUSE returned on unanswered MT Call ...................................................................... Patch Set 2: (1 comment) Patchset: PS1: Looking at that, and reading the comments, that guard timeout is designed to overall protect against something becoming non responsive: /*NOTE: The purpose of this timer is to prevent the cc state machine * from hanging [......] * So if the cc state machine does not show any activity for an * extended amount of time during call setup or teardown the guard * timer will time out and hard-clear the connection. */ One /could/ start adding conditions to this timer, but I think that might get in the way of it's stated purpose. It would seem that what is more needed is the proper implementation of T301 (I think it is T301) See TS 04.08 5.2.2.3.2 -- To view, visit https://gerrit.osmocom.org/c/osmo-msc/+/28509 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-msc Gerrit-Branch: master Gerrit-Change-Id: I4a9cfc388ec9ecb743d154a114a6db638eac4701 Gerrit-Change-Number: 28509 Gerrit-PatchSet: 2 Gerrit-Owner: keith <keith(a)rhizomatica.org> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-CC: laforge <laforge(a)osmocom.org> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: dexter <pmaier(a)sysmocom.de> Gerrit-Comment-Date: Mon, 03 Oct 2022 18:07:31 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: neels <nhofmeyr(a)sysmocom.de> Gerrit-MessageType: comment
