I setup FreeSwitch as my VoIP server on my router, and let OBi110 to register onto the VoIP server. I found that it will show register fail in 60S after rebooting. The error shows that "No Response From Server"
Here is the syslog information, it looks that FreeSwitch will response the OBi110 at first. While OBi110 success to register to FreeSwitch, OBi110 will always send out a package as "sendto 725bc70f:5080(286)", and FreeSwitch will stop response after it.
