NEC IP Phone Works, One Way

Hey folks,

I am a bit lost, as this is my 1st go around with VoIP. I currently
have a NEC Electra IPK system w/ the VoIP card, etc.

I set the unit up today, and uploaded the latest firmware to the
card. I took the phone to one of my satellite offices about 40 miles
away from the PBX. I got the systems to connect, I can check
voicemail, get an outside line, and page, however nobody can hear
anything that I say, however I can hear the other end w/ the PBX
absolutely fine.

I've blown away the settings on both the card, and on the phone, and
nothing I am doing is working. Is there something I am missing here?
Is there a specific set of ports I need to open on either firewall? I
have the phones set on the DMZ ip's, so all ports apparently are

Any help would be appreciated.
