ePBX can register to another ITSP as a SIP trunk. So that the Subscriber of ITSP can contact with
ePBX-100A-128 and ePBX-100A-128 can call to ITSP.
Step1: Obtain register account
•
We got an account from ITSP with “Line number 070070, Account: 070070, Password: 123123”.
And the proxy address of ITSP is 218.32.223.140, port 5060. Maybe the ITSP also need to provide
“Realm”, so you should also input Realm for the SIP Trunk, otherwise the call from
ePBX-100A-128 to ITSP may be rejected. For more information about “Realm”, please contact
with your ITSP.
Step2: Set ePBX-100A-128 to register ITSP.
•
Input the necessary information in SIP Trunk Reg. page. In this example, our “Realm” is empty due
to our ITSP does not need Authentication for incoming call. For more information about SIP Trunk,
please go to user’s manual CH3- Full Web Configurations.
