Ok, we are seriously looking at replacing our PSTN gateway (a Grandstream GXW 4104 ). We are considering Audiocodes and Patton. Does anyone have any experience with either of these? What are the pros and cons between them? I have found a site where both are ranked highly and have a lot of reviews but the reviews are not viewable by the public. I would appreciate any thoughts good or bad about these two gateways. We are looking for a 4 port FXO gateway so if there are any other suggestions out there I would love to hear them.
