[i18n] Make "Transfer" explicit

"Transfer" can refer to "Call Transfer" and "File Transfer". Could you please make the source language files explicitly have "Call Transfer" and "File Transfer"?

For example, the string "Transfer to" should be something like "Call Transfer" or "SIP Call Transfer". This would help when translating the strings on Transifex where only strings are shown (there is no GUI).

English (2 words) → Hungarian (1 word)
call transfer → hívásátadás
call forwarding → hívásátirányítás
file transferring → fájlátvitel

What do you think?

Thank you
