Known issues and workarounds

Creating a carrier that requires outbound registration does not work because the sip_gateways rows associated with the carrier are incorrectly set to inactive when first created. The workaround is to first create and configure the carrier in the jambonz web portal, including the outbound registration configuration, and then applying the SQL update below.

Note: this bug only affects carriers configured with outbound registration. There is no need to apply the fix below when configuring a carrier that does not require outbound registration.

on VM installs

Use an ssh client to log into the jambonz webserver as 'admin' user. Find the mysql password in the apps/ecosystem.config.js file - look for the environment variable named JAMBONES_MYSQL_PASSWORD. Then, using the mysql client log into the database and apply the update statement as shown below.

on k8s installs

Use kubectl or Lens to exec a shell into the mysql container. Find the mysql password from the env vars for the api-server container. In the shell on the mysql container log into the database and apply the update below:

$ mysql -u admin -D jambones -p
Enter password:
