It seems that the OPTIONS method is corrupted.
According to RFC the OPTIONS should be sent from IP Office LAN address to the ITSP proxy address.
In the trace below you can see both FROM and TO field are the same.
Even better: When check OOS is turned off, OPTIONS are still being sent.
Anyone has an explanation for this ??
