Query is , Do these outputs ensure that we have completed the installation successfully or are there any extra packages or configuration required? The reason for this query is in the installation step(Validating Your Installation - Asterisk Project - Asterisk Project Wiki, following output denoted successful asterisk & dahdi installation.)
