1.
DDI .The ability to have
multiple telephone numbers even with a small number of lines
(or channels in ISDN speak). This allows for fax machines, PDQ's,
private lines, alarms etc. It also facilitates the ability to
answer the phone in different company names and analyse the
response to advertising and this just scratches the surface.
2. CLI . The ability
to see who is calling you before answering the phone. Keep
the telephone numbers of historic callers, (no more messages
taken with miss written telephone numbers). Calls can be automatically
routed directly to the correct department, such as aged debtors
straight to accounts.
3. Fast internet access. Surfing the net (although not perfect)
is significantly faster and less stressful using ISDN.
4. Fast data networking. Two or more computers at different
sites can communicate much faster and more reliably via ISDN
than via modem.
5. Video conferencing. Again not yet perfect but useable
over ISDN.
6. Trunk to trunk transfer. Transferring a call to any other
number in the world, i.e to your mobile, home or villa in
St.Tropez.
7. In today's high-tech age it is not financially sound to
purchase new equipment that is not at least close to the leading
edge. Whatever high-tech equipment is purchased today (telephones,
computers, fax machines, video's, hi-fi's etc) is out of date
in a very short space of time.
The best advice we can give at Phones4Less regarding any
technology is, think of the technology industry as similar
to comparing the age of your dog to the age of a person, i.e
multiply by 7. If an item of hi-tech is 3 years old it is
the same as a low-tech item being 21 years old.
