Please pardon the newbie question, but I can't seem to figure this out.

I followed the Voxilla's tut to the tee: http://voxilla.com/2009/10/15/voxill...p-by-step-1457

But in making calls, my softphones connect, yet no audio (in either direction).

I know from poking around the forums that this is generally caused by two factors: NAT and audio codecs.

I (being new to the arena), however, don't know which. I believe I have Asterisk and the clients restricted to just ulaw, and I also believe I have the correct ports open, and my externip set correctly (I think the Voxilla AMI does this automatically, since it's in the cloud).

I'm a bit lost. I'd be happy to post whatever configuration files that might help, provided you tell me where they are on the filesystem. But like I said before, this is effectively a vanilla install of Voxilla's own FreePBX AMI.

I'd appreciate any help or guidance here. Thanks!
