Restarting CTI Service Manager

[John Ruhl]

Does Restarting CTI Service Manager for a restart of all the phones connecting to Call Manager?

No John, it is not for restarting phones connected to CUCM. If you restart the CTI manager service, it ends/restarts the CTI connection to applications such as UCCX, UCCE etc. However, any CTI clients associated with that phone e.g. softphone, CAD etc will go offline till the service comes back online.

If you wish to restart all the phones, then you will have to manually select them all & click restart from CUCM admin page. Restarting Cisco Callmanager service can initiate phone unregistration & then phone starts looking for secondary call controller ( CUCM or SRST Router ) but it doesnt result in to phone restart.

Thanks for your prompt reply. I did not want to force the phones to restart.

hello,

What logs can I activate in CUCM to see why I had to restart the CTI Manager.  This is for a client who uses CUAC and they wanted to know for the next time why we restart the CTI Manager and what causes the service to go down.

Thanks

Well that depends on the kind of issue you are facing there. Ideally, CM and CTI logs should be good to start with.
