[Asterisk-biz] bridging iaxtel calls to PSTN

[info at cybernergies.com]

Hello,
 I just started using asterisk, and have a question. I have  setup two
asterisk servers, A and B. A has a Digium TDM400 11B card (1 FXO and 1
FSX modules) and is connected to the PSTN. B has same, but is NOT
connected to PSTN. I want to configure B to call A via iaxtel, and
connect to the PSTN using A's line. How can I configure iaxtel dial
plan for B in extensions.conf? I want to be able to make a call to
local US number (where A is located) from B, using iaxtel. Can anyone
please help me? All I have seen so far is just making calls from A to B
and vice versa using the iaxtel 1700 number, but I haven't seen any
examples of how to bridge the iaxtel calls to PSTN. Help please.

NB: I don't mean toll free number, I mean just local dialing.
