OK, now i got your goal:

1.) your "fax-prefix" is 5 (which is the DDIOffset)
2.) your "fax-number" is 00-99 (which are the IncomingDDIs)
3.) your "fax-number" has 2 digits (which is the DDILength)

So, your config should be:

UseDDI 1
DDIOffset: "5"
DDILength: "2"
IncomingDDIs: 00-99

Remember, that the dialed-number passed to faxrcvd is only the 2-digit 
IncomingDDI. The DDIOffset is cut off. When i remember my tests with a 
fritz card right, DDI can be configured but is ignored due to lack of 
protocol support. May be you can increase tracing and have a look at the 
logs after restarting c2faxrecv.

You can also use "UseDDI: 0" and "IncomingMSNs: 500-599", as you need 
the complete number. This should also be the solution if the fritz card 
really doesn't support DDI.

Hope this helps.
