You mean "use SNMP"?  A MIB is something that an SNMP agent  
implements.  Asterisk 1.4 and later has a built-in SNMP (sub)agent in  
the form of res_snmp.

You could approach this one of two ways.  You could enhance res_snmp  
to implement the MIB that you have designed, or you could create  
essentially a proxy that back-ends SNMP requests to AMI.  You could do  
this latter method in C using the net-snmp libraries, in Perl using  
Net::SNMP, in Java using SNMP4J-Agent...

Have you developed an SNMP agent before?  I'm currently working on  
some enhancements to res_snmp (in line with the first suggestion  
above) and would be interested to see the MIB that you have created.   
If it is generally useful, we could adapt it as a branch off of the  
existing Asterisk MIB.

I don't understand this last question.  Can you clarify please?
