How does DID routing work in GFI FaxMaker?

Answer

DID routing through GFI FAXmaker is based on mapping different fax numbers to a particular set of GFI FaxMaker users. The DID can simply be considered as the set of digits which uniquely identify a called party number. We can break down the number received by GFI FaxMaker as follows:

<fixed number> <varying number>

For example:

31312244 101
31312244 102
31312244 103
31312244 104

Therefore, DID routing is based on the varying number part. On receiving a fax, GFI FaxMaker follows the following steps:

1. Incoming FAX is detected

2. GFI FAXmaker retrieves the Called Party Number

3. The MSN list entries are compared against this number

4. In case of an MSN match GFI FaxMaker accepts the call and completes the reception otherwise the call is ignored

5. On completing reception a number of trailing digits from the Called Party Number are identified as the DID. The number of digits to be used are configured from the GFI FaxMaker Server Configuration

6. The extracted DID is compared to the routing tables in order to determine which GFI FaxMaker users are to receive a copy of the fax
