Redirecting Number for Offnet Voicemail

[5essfun]

Dear Telefolks,

How can the 87XX or Definity Switch be configured for off-net voicemail, such that the coverage call ISDN SETUP message going out a PRI will contain the "Redirecting Number Parameter" and "Redirecting Number" information element, allowing the call to get to the correct mailbox when the call is routed to an offnet voicemail platform, Octel CA for example.

Thank you.

Did you try the cama-numbering plan for e-911?

Thanks for answering, but how would this be configured to send RN for Offnet Voicemail? Sorry, I don't see the connection between 911 CAMA and RN for Voicmail.

Thanks.

Does Avaya support "offnet" voicemail?

Thanks!
