TOLL=SIP/YourVoipCarrier

Asterisk Asterisk Support
1

p 149 of Asterisk, the Definitive Guide says that the TOLL variable “…is to simplify management of your dialplan…”. Fair enough, but how does it simplify management?

they have:

[globals]
TOLL = SIP/YourVoipCarrier

fair enough, but what does that accomplish, exactly, that’s advantageous?

Is there some flaw in doing this:

Ok, I see how you can use the TOLL variable in extensions.conf now:

root@mordor:/etc/asterisk# 
root@mordor:/etc/asterisk# cat extensions.conf
[general]
static=yes
writeprotect=no
clearglobalvars=no

[globals]
TOLL=SIP/TELNYX
#include extensions.telnyx.myphones.conf
#include extensions.telnyx.outgoing.conf
root@mordor:/etc/asterisk# 
root@mordor:/etc/asterisk# cat extensions.telnyx.myphones.conf
