Mitel 3300 phone Heartbeat failures

[matthew]

The release notes have been re-released as v2 (they were v1.1 last week). The change section says:

12.0.1.23    2nd version of release notes for MCD 6.0 SP1
  -added 3am Heartbeat loss defects (MN463982/469352/473817/475449)

I'd actually queried this with the TSC last week, as they assured me the fix was in, but the release notes didn't mention anything. I'm not sure why the release itself is gone though.

I had an open tick re the 3am failures. I am assured it is fixed in 6.0 SP1. Was released on may 30 then removed then next day. There are SIP issues with the release.

MCD6.0 SP1 is back on MOL. Now 12.0.1.24 (the pulled release was 12.0.1.23). Release notes have also been bumped to v3.

This looks to be the culprit for the disappearing act. 

MN00483821 SIP devices cannot make calls after all SIP channels get stuck in releasing state.
REPORTED IN SW LOAD - 12.0.1.23
SYMPTOMS
Make numerous SIP calls. The channels get stuck in releasing state until all are in this state. Eventually SIP devices cannot call other SIP devices

I know the tread is about the heartbeat failures, but does anyone knows if the issues regarding the SIP channels getting stuck have been solved with the release of MCD 6.0 SP1?

I believe the SIP issue is fixed now. Had a site with the issue and product support suggested the upgrade to fix. Problem is its a cluster of SX2000's and 3300's so stuck at MCD 4 unless we want to break the cluster into two.
