I've been trying various setting with my Asterisk, and it seems that the only way to register to the HKBN 2B network is by adding the the following line to the /etc/hosts file (as described in the voip-info.org forum)
203.80.89.135 s2hkbntel.net s21.hkbntel.net
I really like the VoXalot service, but if it doesn't work with hkbn, then I might have to turn on my asterisk box and pay that extra money for electricity bill and bear with the heat and noise the box generate.
