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.

Strange?!? These three phones are using g726 (this codec is configured in sip.conf and in SIP ATA as well). ---------------------------------------------------------------------- Zostan Dziewczyna Lata! >>> http://link.interia.pl/f1997
Try changing the configuration on your PAP2 linksys, more precisly the part where is the NAT parameters, try changing the options from NO to YES. -----Mensaje original----- De: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] En nombre de andrutto Enviado el: Mi?rcoles, 23 de Agosto de 2006 03:41 p.m. Para: asterisk-users@lists.digium.com Asunto: [asterisk-users] NAT problems Hi, Does anyone know how to solve this issue.
