If you are unsure what your PBX or the PSTN will be sending to the gateway, you can place
a couple of test calls into the gateway and look at the call log to see the information that is
being sent. The calling party information can be seen in this screen shot which shows a call
from extension 1111 to 425-882-1234. Be sure to place calls from both on the PBX and from
outside. It is possible that you will receive a 4-digit number from inside and a 10-digit
number from outside. If this is the case you will need to enter two rules one for each number
format.
