If not using a local IP Office trunk for emergency calls, the IP Office must use the Avaya Cloud Office™ E911 Emergency service for emergency calls. When using that service:
Warning:
Certain events, including the following, can prevent you from reaching emergency services:
An Internet or power outage.
If your broadband, ISP, or IP telephony services are suspended or terminated.
Suppose you are in a country other than the one in which your IP line to Avaya Cloud Office™ is provided. For example, if you have a US line and travel to the UK, you cannot reach the UK emergency services number.
Suppose you are in a country where RingCentral is not permitted or cannot complete emergency calls.
If there is network congestion that delays or prevents completion of calls to the emergency services.
