Caller ID is displaying as UNKNOWN, ANI issue

Post by headpill »

Hello,

We are passing provider's number as ANI number which is available to vxml but still the Caller ID is displaying as UNKNOWN when call comes to recipient's phone. We do not have production account, and we are suspecting that it could be a restriction, otherwise anyone can place a call using someone's number.

If that is not the case can you help us what could be wrong, where to look for, if you have any samples.

Only thing we see in documentation is -

To specify the caller ID on a per call basis, you'll have to change your phone_number parameter to also include the caller ID you want the call recipient to see. The format is: phone_number=tel:+10123456789;ani=1234567890 (This would make an outbound call to 012-345-6789 and display a caller ID of 123-456-7890). The 'ani' must be a 10 digit number, without the preceding '1'.

which is not very helpful.

Please advise.

Thanks.

Hi,

The value "UNKNOWN" would be displayed by a caller ID when it is attempting to determine the name of the caller based on the ANI. There could be a couple different things happening which is causing this affect:

1. The caller ID does not know the name for the supplied ANI, thus it displays the text "UNKNOWN".

2. The far-end carrier does not support masking the ANI, so the ANI for your account is supplied to the caller ID and then issue 1 occurs.

For either case, we cannot affect what is ultimately displayed on the caller ID.

Regards,
