> Hi,

> I'm using SER with Sipura and VoIP GW.
>
> When there is no line available from the VoIP GW, the VoIP GW replies with
> 486 Busy Here.
>
> The Sipura receives this message and sends an ACK.
> The ACK has the IP addr. Of the SER. Is it ok, or it should be the IP
> address of the VoIP GW. When SER receives the ACK with its IP address
> 192.168.20.155 <http://192.168.20.155>, there is a loop of ACK in
> SER.........
