How to Control Timers and Events to Prevent Alarms and Disconnects
First of all, it’s important to note that most issues with switches and servers showing red/down in Director, and thus creating alerts are network related. This KB article goes in-depth very well at exactly what’s going on with switch to switch and switch to server communication and how to troubleshoot/eliminate network connectivity as a suspect.
There are built-in time-out settings for protocols like TMS and we are able to override most settings via the Windows registry on the headquarters server.
The default time-out for TMS is 90 seconds. If we don’t complete a ping/response in that time, the switch is marked as Lost Communication. We can add a registry entry to increase this time-out duration (a max of 180 seconds is recommended) which alleviates most false-positive alerts in Director.
DRS sends a ping every 40 seconds and waits up to 10 seconds for a reply. DRS will constantly send pings, even if the feature is not in use. This doc is pretty old, but describes DRS functionality pretty well: https://oneview.mitel.com/servlet/fileField?entityId=ka61A000000GuoSQAS&field=Public_Facing_Attachment__Body__s
CAS is mostly related to client-side functions like the Connect client and IP phones. It’s used to connect to server-based resources (like pulling up the directory, retrieving call history, accessing visual voicemail, etc.). All clients maintain a “CAS Ping” which is their round-trip time through their CAS server, but the value is only useful for troubleshooting.
Mitel Connect and TLS 1.2
TLS 1.2 is supported in the most recent version of Connect (22.12.7211.0) that will be Generally Available (GA) by the end of September 2020. Packet Fusion is currently running this code as we are in their Beta program and all is good.
What do you need to do to take advantage of TLS 1.2?
- Upgrade to the current connect build.
- Make sure there are no older SG vintage switches in your environment as they do not support TLS 1.2: (SGT1K, SG30, SG50, SG50V, SG90, SG90V, SG220T1, SG220T1a, SG24a).
- By nature MGCP will not support TLS 1.2, so all MCGP phones will not be supported: (IP110, IP115, IP230, IP230G, IP265, IP560, IP560G, IP565G, IP655).
- The switches that do support TLS 1.2 are: (ST1D, ST2D, ST24a, ST48a, SG50A, ST100A, ST100DA, ST200, ST500).
- Virtual switches support TLS 1.2
TLS 1.0, while not as secure as 1.2, will be supported in Connect until the SG switches go End of Support which is slated for some time past 2024.
TLS 1.2 is not new to Mitel as both the EdgeGateway and Mobility Router both utilize it.

How Microsoft’s Depreciation of LDAP Will Impact your Mitel/ShoreTel System
Microsoft has announced that soon they will depreciate LDAP in favor of LDAP-S, which is much more secure.
Active Directory (AD) uses different ports for LDAP vs. LDAP-S which means that when LDAP is disabled some work will need to be done on your network and on your Mitel system to ensure that AD integration continues to function.
Before Microsoft pushes the final Windows update for Active Directory that will disable LDAP, Mitel will issue a patch to enable support for LDAP-S on some of their most recent on-prem software versions. Applying this patch to your Mitel system will require that we install software on your HQ server and then reboot it.
LDAP-S is supported today in Connect from Release R19.1SP1 (22.11.4900.0) to Current. The patch referenced above will be made available for prior releases R19.1 (22.10.7600.0) and R1807SP2 (21.90.9743.0). If you have a release prior to R1807SP2, you will need to either disable Active Directory for your users, or upgrade to the most current Connect version. Mitel has not yet confirmed at this time whether they will have a patch available for ShoreTel 14.2. If that patch does become available, it will only be for the final ShoreTel 14.2 release (GA30, build 19.50.1000.0)
The good news here is that Microsoft has delayed the update which disables LDAP to a yet-to-be-determined future date. We know that it will happen eventually, we just don’t know when.
We have no way of knowing whether or not you are currently utilizing AD on your Mitel or ShoreTel phone system and want to be proactive in getting the patch implemented before Microsoft disables LDAP, so we are reaching out to our base and starting our list of customers who will need this patch. Please send an email to email@example.com to let us know if you use AD so that we can determine what action will be required to keep AD integration working for your system.
As always, we reserve the right to change any of the above as Mitel or Microsoft release more information.
If you have any questions, please reach out to your sales rep or client services rep (firstname.lastname@example.org) or to me email@example.com for a one on one discussion.
Adobe Flash Depreciation and Mitel Connect
Adobe Flash will reach End of Life December 31, 2020. What does that mean for you and Mitel Connect?
Mitel Connect uses Flash for several applications for administration purposes: Edge Gateway, SA100/400 and Mobility Router, however all major browsers will drop Flash support from updates on December 31, 2020.
Mitel is 30 days away from releasing patches that will replace and reboot a file in the applications, so they will not use Adobe Flash. It is our understanding that the patch will be available for both Connect and 14.2. and that the core ShoreTel system does not need to be rebooted.
If you choose to upgrade your browser after December 31, 2020 and prior to installing the above patches, the applications will continue to work, but you will not be able to administer the applications.
If you are being monitored by Packet Fusion with our Kaseya monitoring offering, we will be able to identify which applications you have and will be in contact with you to schedule the installation of the patches. If you want to get ahead of curve and get on the list, please send an email to firstname.lastname@example.org with your company name and which of the above applications you have.
We reserve to the right to change and amend any of the above as more information becomes available from Mitel.
As always you can reach out to your sales rep, email@example.com or me firstname.lastname@example.org for a one on one conversation about this.
