Is there any variable to change from %%blffirstname%%... ?

[egaulue]

Dear community,

We used to show: UPPERCASE(first letter of the lastname) + "." + " " + firstname

It looks we only have %%blffirstname%% and %%blflastname%% with 3CX. Is there any way to work on it?

We would have love to have %%blfnickname%%, but it looks it doesn't exist. We though about using SIP ID, but no success too.

Is there any way to say: "Just take first letter" or "uppercase"... ?

Any idea ?

Best regards,
