I have a weird problem that no-one up to now has been able to answer, can any of you help.
Looking in the logs - SIP Peers says:
sipgate.co.uk:5060 USERNAME 120 Request Sent
I am not able to connect - using IAX this works.
I think the problem is something to do with my firewall, looking in the logs I see that all my outbound routing is working no problems the data is being sent.
When sipgate send data to me I see the source port is 5060 but the destination port is 0. but it wants to send it to the correct IP address.
Does anyone have any ideas or suggestions? I am using Kerio Winroute firewall as the router and firewall.
Any ideas or suggestions would be welcomed - If needed I can provide further information about our config.
