Step 5 (For MGCP mode only) Capture packets to view the digitmap of the softswitch in the MGCP
mode.
The softswitch sends the digitmap to the IAD in the RQNT message, as shown in Figure 2-2.
If the number length in the digitmap is configured to 11 digits, but the called number consists
of 12 digits, only 11 digits of the called number are reported. Therefore, an incorrect number
is reported. Check whether the digitmap is correct.

If no, modify the digitmap configuration on the softswitch.

If yes, go to Step 6.
