My OBi110 has registration error with ATCOM IP-01 (Register Failed: No Response From Server) after 60s re-boot. Please advise what configuration is needed.
I setup sp1 for Google voice and sp2 to my IP-01. Everytime I reboot OBi, registration for sp1 and sp2 are successful. After 60 seconds, OBi re-registration but this time failure. I have no registration problem for the same IP-01 account in x-lite or other SIP client.
Router port forward to IP-01 was done before. My router with DD-WRT firmware. The problem is only happen during re-registration. I will try to change another router for testing.
