Symptom
Customers experience call rejections due to spam flagging by US carriers on their outbound traffic.
Applies To
- US Voice Traffic
Resolution
- To improve the delivery rate, the first and foremost recommended option is to ensure a callback set to the outbound LVN. This could even be a simple IVR messaging indicating the purpose of the calls from the Virtual Number or the organisation's details about the origin of the calls.
If calls to specific operators are flagged, we recommend registering the virtual number on the following specific provider portal to prevent flagging.

Additionally, registering the LVN on the First Orion.com portal before the calls are flagged as spam reduces the impact of Spam flagging by providers.
