When a particular user (for example 123@foo.bar) need to call to PSTN, we need to sent in the "From" part as 456@foo.bar, because the PSTN provider needs the 456 to authenticate.
this comes up almost every week on the mailing list. please check the archives. the sort answer is: add rpid header instead of modifying from and ask your pstn provide to use rpid instead.
