I tried to follow the documentation and verified that indeed it does not
work.
It appears that asterisk is unable to connect to the AgentX socket of snmpd.

This appears to be a permission problem, since asterisk drops its
privileges.

The agentXPerms configuration directive of snmpd.conf (as suggested by
Asterisk's documentation and snmpd's man page) is supposed to call
chmod/chown to alter the permissions of /var/agentx and /var/agentx/master.

This is not however the case, presumably due to a bug of snmpd.

To workaround this bug, try to change the permissions of /var/agentx and
/var/agentx/master. For example
	chown -R asterisk.asterisk /var/agentx
This is far from ideal, since you'll have to execute this every time
snmpd is (re)started.

I'm reassigning the bug so that the Net-SNMP maintainers can have a look.

Thanks,
Faidon
