[asterisk-users] A way to check against a list of numbers?

[Jose P. Espinal]

Hi,

If you have those numbers identified (no matter what the number pattern 
would be, but you know which will go to DAHDI, and which to SIP) and 
grouped somewhere, you could insert that information into a database and 
use AGI in order to set the proper technology to use in each case.


e.g
Having a table like:

+-----------------+
| numbers_list    |
+-----------------+
number        <---- insert the number
tech          <---- indicate the technology, e.g. 1 = SIP, 2 = DAHDI

In the moment you are about to dial the number, you can have AGI to look 
for it in the DB, depending on its 'tech' field you set a channel 
variable to the proper technology, and then just dial the number.

That could be a solution.


Additional suggestions:
a. If you take this approach, you could add a primary key to the table, 
and set the 'number' as index. (This is not related to Asterisk)

b. If you can do this using C, Perl or Python; it would not (possibly) 
represent a considerable performance hit to your system.
