How to send a manually generated sip request via asterisk?

Question

Asterisk

To de-register an outbound trunk, you need to send specific sip requests. There is a configured asterisk. I realized that I need to send INVITE with expiration=0
I read RFC3261, there seems to be nothing complicated. However, it is not clear what tags to search for sending sip requests manually? Please tell me, I really want to advance in this direction, but I can not find mana.
Of course, there is another way - changing the configs according to the script, followed by a reload. To do this, you will need to write a parser, as I understand it. If the asterisk has a function to dynamically change its configuration files (ie, using the built-in parser), please tell me.

Answer 1

Well, why not curl from the script?

Answer 2

Asterisk DOES NOT have the ability to change the configuration on the fly, but it IS possible to generate the configuration with a script while (re)loading specific configuration files. So it’s really possible to do reload at the right time, and generate the actual configuration, for example, with a script.
