Thank you all for your input.
I told the customer that the conversion attempt would be "Best Effort w/ No Guarantees"
I haven't heard anything back......🦗
Hello Shaun,
Thank you for your response.
Would you be able to provide or tell me the firmware version that would be required to register this phone to an on-premise system?
Hello,
A customer recently purchased a DT900 ITK-32-LCGS-1 from Ebay and requested that I assist in registering it to their SV9100 CP10.
I factory defaulted the phone and attempted to register it the way I register all other IP phones with no success.
Is this model of DT900 compatible with a...
Does anyone know if the SV8100 DT300 / DTL-8LD-1 phones (desi-less) will function on a SV9100 CP20?
I have a customer that would like to upgrade from the SV8100 and was wondering if their existing phones will work on the SV9100.
Thank you for your input.
Hello CoralTech,
No evidence of a DOS attack has been detected.
The site is not currently using vm to email.

Hello timqa,

Hello Wylie13,
A port mirroring switch could be installed between a troublesome phone and LAN cable to it.
Then connect a laptop to the mirroring port running a countinuous ring buffer capture file.
See attached docs...
Watch and observe when the phone went offline and analyze the captures...
Hello Wylie13,
I think the simplest way to start is obtaining the current IP addresses of the DT900 IP phones that are experiencing the issue.
Then work with your CrowdStrike admins to white list the IP addresses and monitor to see if the issue has been resolved.
Hello Wylie13,
Just a thought......
I recently installed a few older DT700 IP phones to a SV9100.
The phones came up and worked fine for a period of time then would show a screen with a message of "Log Off" until you press soft key for "Exit" and the phones would reset and work properly...
Hello conxtel,
I'm not sure if it's related, but on SL2100 systems, if the alarm logs show "Memory Backup Bat." and the site experiences power fluctuations, sections of the programming will go into default.
Also, on a few SV9100s, I have witnessed sections of the programming going into default...
