Hi
I have Ser Express router on a Public ip address with no firewall between it and the internet. I have two hardware phones and two software clients connecting to the SER box.
All 4 clients are on a private network with Nat connecting to a gateway on a public ip address in the same range as the Ser Unit.
They register and I can make calls between these 4 clients.
When I go to a remote location on a different ISP.
I check the computer is on a public IP and no firewall is enabled. I place my SER details for registration into the client and it fails to register.
I tried xlite with its debug screen and I see the send but note no response.
When I use ethereal I capture the send but note no response packet received.
I have tried a couple of port scans from the internet and I confirm port 5060 is open and listening.
I have an Asterisk box on a public ip address also in the same range as the SER unit. It registers to SER and ser routes calls to it and bridges SIP - H323 out to a Gatekeeper and calls work within normal limits.
What am I doing wrong?
SERWEB is working and the website etc. all work from the internet no issue.
