External Caller ID
The outbound caller ID is the number that will be displayed to the receiving party when an extension from your PBX makes an outgoing call.
IMPORTANT
If the Outbound Caller ID is different from the E911VERIFIED number for the PBX or extension when 911 is dialed, the Outbound Caller ID for that extension or PBX will be changed to the E911 VERIFIED number assigned. See E911

In an effort to protect consumers against abusive robocalls, carriers are increasingly implementing call blocking programs. In recent weeks, Bandwidth has observed AT&T, Verizon and T-Mobile increasingly blocking calls that they feel fit typical robocalling campaign characteristics, such as high-volume, short-duration calls originating from a single number. When implemented, a common effect of these call blocks will be a very high volume of SIP 486 (Busy Here) response codes being delivered. There are many, many legitimate use cases for high-volume, short-duration calls, including school closing notifications, weather alerts, and patient reminders. These are entirely valid and legitimate use cases where recipients want to receive these calls and have opted-in to do so. However, when viewed en-masse at the network level, they can look like illegal robocalling. In order to ensure your outbound calls aren't miscategorized as unwanted or fraudulent calls by the wireless carriers, we highly encourage you to proactively request whitelisting of legitimate outbound calling use cases from each of the major wireless carriers. Here are the websites where you can submit whitelisting requests:
