We receive Fax via Email. To have a better searching experience in Outlook (or whatever you use), it would be handy, if 3cx would check the companies address book for the callers id, resolve the callers name and add it as a new parameter (%%CALLER_RESOLVEDNAME%%). This could then be used in the "from-field" for example. Additional there could be a even new variable %%CALLER_RESOLVEDEMAIL%%. This could maybe be used to enable direct email-replies for inbound faxes.
