 In Branch IP PBX, set up routing table as follows. So the user in Branch can call
extension 301 which is located in Branch .
Now the extensions of these two ePBX80 can call each other.
There is an important thing you should pay attention. All the numbers of HQ and Branch should
be unique. For example, there is an Extension 401 in branch. If you hope user in HQ can contact
with 401 which located in Branch, there should not have any number equal to 401 in HQ, including
Extension, Trunk, Dial Group…, etc.
Case 2. Call local PSTN number between two ePBX80s
Suppose in Branch office local PSTN area code is 02, number is 8xxxxxxx, HQ local PSTN area
code is 04, number is 2xxxxxxx.
Step1: Set up outgoing routing
 In HQ, set up routing table as follows. The Prefix code is 02; Digits Length is 0; Drop is
2, so the user in HQ can call PSTN number 028xxxxxxx which is located in Branch . The
ePBX80 will drop 02 first and then send 8xxxxxxx to Branch. See the following webpage
