Re: [hylafax-users] Receiving Remote TSI name string (vs. remote number)
I may be off on this one, but I think if the sender doesn't setup their
TSI it will automatically default to the sending number. (?) If the
number is unlisted or has caller ID blocking, it may show as 'UNKNOWN' or
'UNSPECIFIED' or even just blank.
I have received some faxes with an ASCII text TSI, but most are numerical
phone numbers. There was nothing I did on my end to change this, it was
just how they come across.
Steve Friedl's Unixwiz.net Tech Tips writes:
During the initial setup of the call, both stations swap ID strings:
CSI - Called Subscriber Identification
TSI - Transmitting Subscriber Identification
The answering machine announces its CSI string to the caller, and the
caller responds with its TSI string, and they are typically phone
numbers. The fax specification (CCITT T.30 184.108.40.206.4) limits these
strings to 20 characters from the set "digits, space, and +". But in
practice, almost all fax systems allow full ASCII.
Based on what I've been able to research, the receiving end has nothing to
do with the TSI.
