Post ISDN PRI: "Redirecting Number" in SETUP for EC500 call

The telephone service provider has inserted an ISDN<->SIP converter between the MM710B and the public telephone network at one of our customer's sites. Since then, calls which tandem through the Avaya Media Gateway (typically EC500) have their outgoing leg disconnected by the public network. The service provider says that we should either include a calling party number from the site's DDI range or include the "Redirecting Number" IE in the outgoing Setup message. I have activated SA8052 and SA8146 but do not see the "Redirecting Number" IE. Thanks in advance for some ideas on this issue.
