We have been using RDP profiles more lately now that our campus has fully migrated to CUCM. I would like to fully understand how this service works with regards to cell phones.
We have a situation where RDP profile is set with the following timer information setttings: 4 seconds delay before ringing cell phone, 1.5 second delay to prevent call from going straight to phones voice mail, and 19 second delay before stopping ring on the cell phone before going to cell phone voice mail.
With these settings on a specific number, when the cell phone does not have service or is dead, what should happen to the call? Should it ring on the Cisco phone and not detect the cell phone? When tested it was going straight to the cell phones voice mail and not ringing on the Cisco device.
Please advise on how this feature works and what are best practices?
Those settings mostly depend on your mobile carriers and their timers, they need to be fined tuned by testing on your deployment, and depending on the behavior you want.
With those settings, assuming the carrier directs you to some sort of message (not available) or to the carrier's VM, the call to the mobile will be dropped as it was answered in less than 1.5 seconds.
The internal phone, will still ring, those only affect the SNR devices.
