This card connects our analog telephones and offers network telephone services to us. Its performance is excellent. Until now I release this review, and it still works as it comes the first day. Very good value for the money.

I purchased this telephony card for my PBX-U502 so I could take advantage of the VoIP network solutions. The Installation was straightforward and the card was detected quickly without any issues. I also bought another FXS board 2 port version of this card to match them together.

We are so surprised to find that these cards are hot-pluggable, plugging and unplugging phone cards requires only a few screws, so convenient.

The quality is really good, and the delivery is fast, we use it with other types of cards, like fxs. highly recommended!!!

Bought to use with my PBX-U502, two RJ45 ports, connect a 1 in 4 converter that divides it into four RJ11 ports, and then connect the analog telephone lines. it works well.
