asterisk users - Jan 2015 - Dialing from phonebook, and hiding the dialed number from the user.

Hi,

does anyone have a recommendation for a SIP phone, which
allows dialing from a phonebook, and hiding the dialed number
from the end users? Also from the call history of course.

It seems Mitel can do this, and I have a use case where this is
a requirement.

Thanks,
Antonio

I don't know about a phone that can do that, but I can give you another 
possibility that might be an acceptable substitute.

You could alias the numbers in the phone so that in Asterisk they do 
something different. In the phonebook you would have something like: Bob 
Smith: 1000. Then in Asterisk, you have as part of your dialplan that 1000 
would dial Bob Smith's real number. The user of the phone would only ever 
see the number 1000 associated with Bob Smith. The history would still be 
there in the phone, but again, it would just show 1000 as well.

How far you take this would depend somewhat on how often the underlying 
numbers change. You could hard code the numbers in your Asterisk dialplan 
or you could plug them into a database so that they are easier to change 
in the future. Would that work for what you need?

If I have this right, you want to make sure the number can *only* be called 
through your Asterisk system  (so the call gets recorded)  and *not* directly 
from an agent's mobile phone or similar  (so they cannot make off-the-record
calls).

Why not just use Asterisk itself to give the number an alias?  So the end user 
dials some number that connects them to the destination, but of course it 
won't work from anywhere else besides your configured Asterisk system.


My home Asterisk installation  (yes, some people are crazy enough to play with 
phones for entertainment :) )  includes aliases to call people in the village 
where I grew up, using their old 4-digit phone numbers  (even though those 
numbers have now grown to 6 digits, and I have moved across an STD code 
boundary).  Also I have a friend whose mobile number ended with 911, so it was 
too delicious to avoid using that as an alias;


exten => 911,1,Dial(${GSM}/07xxxxxx911)
exten => 911,n,Hangup()

exten => _[23]XXX,1,Dial(${GSM}/0128373${EXTEN})
exten => _[23]XXX,n,Hangup()


If you need many aliases and this is going to look messy in your dialplan, you 
could always use an AGI script to look up the number in a database.

Hi AJ,

Yes, interesting idea, thanks!
