[asterisk-users] Fax pdf attachment naming badly when no caller id on zaptel

[Warren (mailing lists)]

I just installed a Digium TDM04B card.  The lines that are plugged into 
it do not send caller id.  As a result (i believe) of no caller ID, the 
name of the fax pdf is ".pdf".  The subject is "Fax from".  Windows 
clients do not like opening files with just an extension.

Is there a simple way to change the name if it comes in blank?

TIA,
Warren
