5 out of 5 eggs

Pros: Works well, supports T38 FAX protocol, supports two lines when you have two VOIP supplier accounts

Cons: None so far

Other Thoughts: Bought this to replace a Linksys PAP2T interface. The PAP2T did not support T38 FAX protocol. Attempts to send FAX over voice protocols failed due to jittery packet-losing IP service provided by Comcast. T38 protocol worked fine in the lower-speed 9600-baud mode on my FAX machine. I have not tried the higher speed 14400 baud. It may work also; don't know.

5 out of 5 eggsGood Buy

Pros: Updated Firmware to out of the box. Tested 2-way fax, wireless phone, CID without issue. Setup independent sip extensions\routes on each port for simultaneous testing of both functions - no problems so far - base sip setup, 5060, udp, modified rtp range

Cons: none at this time - even the base it comes with fits much better than most
