Asterisk 17 to 18 Upgrade Notes
You might be impacted by the upgrade to Asterisk 18 if you have:
- custom Asterisk configuration
- custom application using AMI or ARI
- custom Asterisk modules (e.g.
codec_g729a.so)
If you find yourself in one of these cases, you should make sure that your customizations still work with Asterisk 18.
In particular, if you are using custom Asterisk modules, you'll need to either obtain the Asterisk 18 version of these modules or recompile them against Asterisk 18. Not doing so usually leads to major instability issues in Asterisk.
