[asterisk-users] NAT problems

[andrutto]

Hi,

Does anyone know how to solve this issue.

I have Asterisk box on public IP and three clients connected to it. Unfortunately they are behind NAT (simple one-to-one). Those three  clients can make outgoing calls hassle free, but when I try to make a call between them something is not right. I am using Linksys PAP-2 (two clients are connected to it) and one phone connected to planet VIP-156. When I try to make call between the phones connected to Linksys I am getting "488 Not Acceptable Here" and when I try to reach the phone connected to planet I am getting silence after answer, but the phone can ring so I think that it is a RTP issue.
I know that it is caused by the NAT, does anyone know how can I configure this to work appropriately.

Cheers

Andrutto
