SELinux is preventing /usr/sbin/asterisk from 'name_connect' accesses on the tcp_socket port 2126.

*****  Plugin connect_ports (92.2 confidence) suggests  **********************

If you want to allow /usr/sbin/asterisk to connect to network port 2126
Then you need to modify the port type.
Do
# semanage port -a -t PORT_TYPE -p tcp 2126
    where PORT_TYPE is one of the following: festival_port_t, dns_port_t, postgresql_port_t, sip_port_t, snmp_port_t, kerberos_port_t, ocsp_port_t.

*****  Plugin catchall_boolean (7.83 confidence) suggests  *******************

If you want to allow system to run with NIS
Then you must tell SELinux about this by enabling the 'allow_ypbind' boolean.
Do
setsebool -P allow_ypbind 1

*****  Plugin catchall (1.41 confidence) suggests  ***************************

If you believe that asterisk should be allowed name_connect access on the port 2126 tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep asterisk /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
