Planet VIP-156PE 802.3af PoE SIP ATA Analog Telephony Adapter 2 RJ-45 T.38 FoIP

This SIP adapter produces a low ringer voltage. Some phones won't ring.

I cannot configure this to work. I have configured many VOIP and FOIP devices over the years but this one was impossible.

Perfect PoE FXS port for RJ-11 to RJ-45 SIP function! Very happy with this adapter.

Easy to configure.

Can't say enough good things about these devices. Moving away from a Sangoma FXO card in a physical server, looks like finally will be able to virtualize asterisk with these devices. They work flawlessly. Standard PoE (48v) on them works great.
