Hi Carlos60,
The *98 that you are entering is also used by the Obi for Blind Call Transfer. So when you are entering *98, it is likely thinking you want that feature instead of passing the *98 on to your SP1 provider.
In your OBI, see the following:
Star Codes -> Star Code Profile A -> Code28 -> *98, Blind Transfer, coll($Bxrn)
You could try to disable this and see if that will help. If not, then you will need to modify one of your digit maps to account for this *98 option. We may even have to set up a speed dial to workaround this.
