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, there is a loop of ACK in SER.........
I attached a trace and this is my configuration.
192.168.20.155 is the SIP Proxy
192.168.20.105 is the VoIP GW
192.168.20.90 is the Sipura
