what does the ! character do at the end of a line ?? Does it invalidate the code ?? It looks like the code beneath template section is without the “!” character
Here is a sample from a sample section on endpoint templates:
It is an ! in parentheses and it means that the section doesn’t result in the creation of an actual endpoint, just provides template parameters that can be referenced in subsequent definitions.
It would probably be better if you collected all your questions on interpreting pjsip.conf into one thread, although templates are not specific to that file.
Configuring chan_pjsip
Take a minute to look over the pjsip.conf sample file if you haven’t already. Then backup your pjsip.conf file and create a new blank one.
Apologies – I looked through more of the online docs and found the explanation that the ! character prevents the code from executing the code — (can you tell I have never used Asterisk before ?
The exclamation mark indicates to the config parser that this is a only
a template and should not itself be used by the Asterisk module for
configuration. The section can be inherited by other sections (see section
“Using templates” below) but is not used by itself.
