Asterisk on fedora 36 (20221108 - updated 20221225)

With this setup I was able to call from one phone to another

only install the necessary packages -

asterisk-18.4.0-1.fc36.5.x86_64
asterisk-pjsip-18.4.0-1.fc36.5.x86_64
asterisk-sounds-core-en-1.6.1-11.fc36.noarch
asterisk-sounds-core-en-ulaw-1.6.1-11.fc36.noarch

my /etc/asterisk/pjsip.conf - which works with cisco spa504g phones as well as soft phones

I had to add "remove_existing=yes" or I sometimes can't reregister a phone if it has already registered.

phone setup for Cisco SPA504G

for extension1, using line1, using asterisk extension 602, based on the config above, here are the extension settings:
- sip settings -> sip transport: TCP - proxy entry needs to be set to: 192.168.1.89:5060
- display name: 602
- UserId: 602
- password: 602
- Auth Id: 602
- Use Auth ID: yes
note that an extension can be mapped to 1 or more lines (buttons) on a phone. This can cause confustion. The mapping is done on the phone tab
