I'm a little bit new in this forum and with Alcatel OXE administration, so i'll try to explain my problem the best way possible that i can

I have a problem with the name displayed on the phones registered in OXE(s) of my client when the call comes from an Avaya (External project and no administrated by my company). When the phones from AVAYA call to the phones from OXE, in this last ones it's displayed the phone number instead of the user's name.
I have the two servers connected by a Trunk SIP in a External Gateway, and The user's name its sended from AVAYA in the field "FROM".
The trunk group created is a T2 type with Q931 signal variant : ABC-F, (I tried with ISDN all countries also but it fixed nothing)
I tried to change the fields: P-Asserted-ID in Calling Number and Trusted P-Asserted-ID header from true to false, but nothing changed in the display presentation.
i hope that someone can help me to fix that.
So thank a lot from now to everybody!
regards.
