The extensions.conf was based on the context name in the sip.conf file (B flag).

Please check out the example in extensions.conf as following:

In “extensions.conf” file,

[Max]

exten => 886001,1,Dial(SIP/886001,20,Ttm)

While the clients send the number 886001 to Asterisk, it will find out the

matching rule in the extensions.conf and decide the destination here.

The number 886001 will be sent to the name 886001 (A flag) with the SIP

protocol. The first emotion is dialing and timer for timeout is 20s.

Regarding to the other flags just like “Ttm”, please get more detail info from the

Asterisk web site about the parameters using in extensions.conf file. “T” is for

the Absolute timeout, “t” is for the timeout and “m” is for the coloring ring back

tone function.
