itself, enter dynamic.

exten => name, priority, application()
Example:
[myphones]
exten => 10,1,Dial(SIP/10,5,r)
exten => 11,1,Dial(SIP/11,5,r)
Explanations (for lines 1 and 2 in the example):
•[myphones]
Context grouping several extensions. Other sections refer to this context, e.g. in the file
sip.conf.
•exten =>
This indicates that one step of an extension is defined. Extensions define how Asterisk is
to act in case of an incoming call or if a certain number is entered in a channel.
•10
Extension number. If this number is called, the actions defined in the corresponding exten-
sion are executed.
•1
Priority of this step of the extension. An extension may consist of several steps executed
in the order of their priorities.
