Today i aksed me the same question - i found a reply here

https://forum.opnsense.org/index.php?topic=21998.msg104097#msg104097

There is not Sip ALG or other ALG.

If found this one too
https://www.reddit.com/r/PFSENSE/comments/jng0dw/has_anyone_else_seen_the_new_nat_slipstream/
and one other reddit posting - saying more ore less opensense does not use any ALG

Not sure if this information can help you.
I read that modern Browser (with new patches) try to reduce the risc related to H323 and WebRTC for NAT Slipstreaming, too
