# Is overhead paging supported on Grandstream ATA?

## Question

Is overhead paging supported on Grandstream ATA?

## Applies To

- HT801
- HT802
- HT812
- HT813

## Answer

These Grandstream models all support FXS. The HT813 is the only model that supports FXO and it's only supported on port 2.

If you have an FXO paging device, configure the assigned user to port 2 on your HT813 as shown in the image below:
