Phone call time out after 12 hours for Doctors transcription. CUCM 12.5

[Rew Waltman]

My doctors are using a transcription phone (analog port on call manager) to call the transcription system which is also connected via analog ports on the call manager. They are getting disconnected after 12 hours. Is there a setting to extend this?

I know, no one should make 12 hour phone call but ...

Thanks for any help.

Adjust the Maximum Call Duration Timer parameter, make sure to read the parameter description.

Thanks, this at least lets me know there is a maximum. I still think the doc's need to take a break.
