What can I try if my router does not have a setting for SIP ALG?
Change the following on your OBi using OBiTALK's "OBi Expert Configuration"
For example, if the SIP account is in SP1
-> Service Providers -> ITSP Profile A SIP
Disable (uncheck) "X_DiscoverPublicAddress"
If the SIP account is in SP2, uncheck the ITSP Profile B SIP -> "X_DiscoverPublicAddress"
