Is anybody using AG-188N? It is a nice little unit, it would be a perfect X-mas gift for your family member abroad. It supports IAX2/SIP with STUN server. Both IAX2 and SIP can be registered at the same time to two different providers. The limiting part is PSTN, it is just a lifeline not a real FXO. The only problem I have is figuring out speed dial setup on these units. I entered in Dial-Peer 123 lifeline 0.0.0.0 0 all:74791270 no suffix 0 but when I dial 123 it does not dial 74791270 I tried entering in Digital Map 123 but it make no difference. -- Joseph
