Suppressing Phone-numbers in Opentalk-Meeting?

[Michael Kuhlmann]

Hi to the list,

when providing an opentalk-conference, currently, phone-numbers of sip-participants are completely visible for all members of the meeting. Is it possible, in terms of privacy, to suppress phone-numbers in a way, that only the last digits are visible and if so, can it be customised from the admin by editing configuration-files of the corresponding server-component?

Thanks and best

Michael
