[asterisk-users] Is there a smarter way to ban expensive calls in dial plan?

Insert your patterns in a database, have a field called expensive, and query
your database before making a call!

[asterisk-users] Is there a smarter way to ban expensive calls indial plan?

Hi, 

try to list the blocked numbers first! 
Then you should be able to use wildcards without a problem. :-) 
That was the solution for the same problem at our dialplan.

  Hi List, 

   

  I need a bit of advice please.  I want to ban calls to expensive destinations
such as cell phones.

   

  This is fairly simple here in the UK because all cell phone numbers begin with
a 7 where as all geographic numbers begin 1 and 2

   

  Elsewhere this is different, take Andorra for example all numbers begin 376,
cell phone numbers are 3763, 3764 and 3765

   

  So if I try the following dial plan my pattern always matches the first wild
card

   

  Exten => _00376.,1,Dial(my iax terminiator) 

  Exten => _003763.,1,Congestion 

  Exten => _003764.,1,Congestion 

  Exten => _003765.,1,Congestion

   

  I seem to have been able to fix this with adding an x after the 6 in the first
extension to make the patterns all the same length and thus making a better
match with the blocked numbers.

   

  Example: 

   

  Exten => _00376x.,1,Dial(my iax terminiator) 

  Exten => _003763.,1,Congestion 

  Exten => _003764.,1,Congestion 

  Exten => _003765.,1,Congestion

   

   

  This is just so long winded, and you can imagine doing this for a huge list of
destinations.

   

  If any one can suggest an improved or more efficient way of doing this, I
would be greatly appreciated!

   

  Best regards

   

  Chris

[asterisk-users] Is there a smarter way to ban expensive calls in dial plan?

Ciao Chris,

This is a common pitfall in Asterisk dialplans: Asterisk doesn't try to
match your extensions in the order you insert them into your dialplan,
but it sorts them out according to its own internal order.

See the CLI command "show dialplan example" to discover how it sorts
them.

So, how to solve this misunderstanding?

You must create other contexts, and include them in your main context.
Asterisk will try to match current context's extensions first, and then
extensions included from other contexts, in the order you included them.

Please refer to
http://www.voip-info.org/wiki/index.php?page=Asterisk+config+extensions.conf+sorting
for further information.

HTH,
