Hi everyone. I'm trying to wrap my head around SIP and Asterisk, and although it's quite an undertaking I've managed to get two extensions on my LAN up and running; placing calls between them works just fine. However, sending SIP MESSAGEs don't. I've managed to track the problem down to "res_pjsip_message.so" not being loaded - and it doesn't seem to be part of the Asterisk stack, either.

That being said, it would be useful to have text messaging enabled in the next release of Asterisk for Home Assistant. Thank you in advance!
