HElP with Sip and Enum!
 

I have registerd a sip sis number on enum. I have tested the lines and it workks good within the united states. In other words when i call a pstn gateway (one that sip broker provides) i get a ring and i get to answer within the united stated. now the reason I wanted this service is because I have friends in the Dominican Republic and I want them to be able to call me. I have an asterisk PBX and when they call They can hear me and I cant hear them and the call drops after 30 or 40 seconds. Can anyone help me in explaining this or tell me if im doing something wrong.

Thanks

Something is probably wrong with your setup. Where do you have the pstn number forwarded to? Your pbx or your extension driectly? Does your pbx have a public IP?
