[Asterisk-Users] Question about context from-internal

[Tielin Xu]

All:

I tested echo test by dialing *43 under Asterisk configured by FreePbx
by using x-lite softphone. I could not figure out how the call is routed
to context from-internal. In sip_additional.conf, I have three
extensions defined as 2826, 2800 and 2801, which all are defined context
as from-internal. FreePbx doesn't define any entry for *43 as an
extension in sip related config files. I greped from-internal for all
configure files, I did not find any definition of context from-internal
in sip related files, except three sip extensions. After I dialed *43,
cdr did show the content of dcontext as from-internal. Can anyone
explain how the call to reach the context from-internal, or how do I get
a context trace for a  call?

Many thanks.
