> Iñaki Baz CastilloHere is a good use case: When you want to hide transfers from ITSPs (many do not like REFER) you need to use a b2bua to keep the signaling local to the pbx that generates the REFER. You can convert the REFER transfer to a Re-INVITE on the ITSP side. You cannot do this without a B2BUA.
