How to make absolutely sure that a cisco Iphone 9971 is able to receive international calls within Cisco Unified CM Administration
System version: 18.104.22.168000-1.
The user has his 9971 linked with his iphone, and the international call from Scotland goes straight to his cell phone's voicemail. Normally a call will will ring about two times on his cell phone, but it doesn't for international numbers. What are the possible problems creating this error. I know partitions allow what type of calls come in. My partition is set as Internal-PT and the CSS is set to allow international calls.
