[Asterisk-Users] limit the length of extensions

[Deon Rodden]

All of my phones use sip, their accounts are in the sip.conf file and 
they have the context of 'company' or whatever. These phones need to be 
able to call each others extension, as well as dial outside to the real 
world. So in that context I put the outbound rules so that the phones 
can call out to the pstn, and I put the extensions of all the other 
phones in that context so that the phones can call each other.

Different companies wanted it different. ie some wanted just local, or 
local and national, or local national and international. Some wanted to 
dial 9 to get an outside line, others wanted to be able to dial without 
the 9. So with the variance, I chose to put customized "outbound" 
extensions per context.
