With the firmware 1.2.1 (Build: 2286), the installation of HKBN 2b credentials can be easily achieved.
Before putting your HKBN 2b credentials on your OBi device, you have to reset your HKBN 2b server to receive NEW registration from NEW geographical location, otherwise registration process may fail.
Using the following link to reset your HKBN 2b account in the 2b server:http://pa.2b.com.hk/login.jsp
It is supposed to set up an HKBN 2b account in SP1 using ITSP Profile A. Other combinations using SP2 and ITSP Profile B can be used if needed.
Please follow the folloing steps to install your HKBN 2b in your OBi deviceService Providers -> ITSP Profile A
1) General -> Name: HKBN 2b
where the Name entry contains whatever name that you want
2) SIP -> ProxyServer: s2hkbntel.net
3) SIP -> OutboundProxy: s21.hkbntel.net
4) SIP -> X_ProxyRequire: com.nortelnetworks.firewall
Voice Services -> SP1 Service
5) SIP Credentials -> AuthUserName: 33445566hk
6) SIP Credentials -> AuthPassword: HKBN_2b_password
With the above settings, my HKBN 2b account can be installed on my OBi110 device without any problems encountered. Outbound and inbound calls with SP1 and ITSP Profile A not only work very well but also the device is able to detect the caller ID as well.
Please note that you may replace s21.hkbntel.net in Step 3 by s22.hkbntel.net for some HKBN 2b numbers.
