| I'll step back a couple of steps. Where the originator and terminator are both PRI, you can pass a calling name, but not in the usual manner. You need to send a special CODESET (I think it is CODESET 5 on Nortel equipment and CODESET 6 on Avaya/Lucent). This codeset (which can contain a name) is sent across the network and can be sent to the terminator as a special codeset. However, the terminating PBX must be setup to accept and translate this CODESET. Also, if you are interfacing with a DMS central office, you need to ask them to map the CODESET to the ATP element of the SS7 message.
If you want to venture this far, let me know and I can give the central office datafill. |
