; define your ports, e.g. 1,2 (depends on mISDN-driver loading order)
ports=1,2,3,4
context = from-pstn
; context where to go to when incoming Call on one of the above ports
msns=*
In the misdn.conf file, I configure the port 1~4 as a group named “intern”. to use these
ports to make outgoing call. We need to add a custom trunk.
Add custom trunk:
Go to FreePBX-->Set up --> Trunks and add a new custom trunk.
Configure the outgoing setting as:
You can also use mISDN/1/$OUTNUM$/b to specify the outgoing call via port 1.
Then add a new route to this trunk and you can make outgoing call via the AX-4S
card.
Add inbound route:
According to the misdn.conf file, our incoming call will go to from-pstn context s
extension.
We need to add a route how it should work for this s extensions.
Go to FreePBX --> SetUp --> Inbound Routes--> Add Inbound Route
