CallCentric free DID+Localphone-->Obi for incoming...caller talks but can't hear

[donw]

I set up a free NY DID with CallCentric and a free Localphone account. After programming in my Localphone sipID and password into SP2 of my Obi, I call my new DID directly from another landline, the Obi-connected phone rings, and the person on the Obi-connected phone can hear me, but I cannot hear them. I've tried the following:
-placed my Obi in the DMZ of my router
-enabled a STUN server in the Obi (stunserver.org)
Any ideas?

Solved! stunserver.org no longer has a stun server running! I simply tried another stun server, and it worked.
