VOIP.MS caller id unavailable
- 
 I have a customer that is using freepbx and voip.ms. They have been complaining that the caller id sometimes shows up as unavailable to the people they are calling. Whenever I have tested it either to my office phone, home phone, or cell phone everything shows up fine. I kind of feel like the people that are seeing unavailable may all be with the same carrier. Can you guys think of anything else that I could be missing here? Thanks

 They used to has phone service with AT&T before I moved them to voip.ms. I wonder if the customers they are calling are on AT&T and the caller id lookup on AT&T's side is empty for their number.

Caller ID unavailable means no caller ID number was passed. Now if @syko24 means that the CID number is coming through, but the CID name is showing as unavailable, yes, that is possible. That would just be a receiving carrier issue.

Customers call my client back and tell them they did not answer the phone because the caller id showed up as unavailable. I believe there is no number or name in the caller id.

 If I have my client call me on various phones I have with different carriers, I see everything you are supposed to see. I do not have an AT&T account so I have not been able to test it there yet.
