Alcatel Unleashed

Hi everyone,

I try to figure out how during a transfer ext/ext I can displayed on the transferred side the number of the first caller.

System: OXO R4

Pictorial explanation:
External User A calls an External User B. User B transfers the call to Ext user C.
I'd like the number of User A to be displayed on User C's phone.

Thank you in advance for your help.

does your provider supports this function?

that must be support by your provider too, some of provider support it just for main number (DDI 0)
