So far I've got pbxes working as it's designed. However, I can't get the trunk for HKBN's 2b service to work. From other forums, I've known that they require at least one specific tweak on the asterisk system.
You need the above entry in your /etc/hosts since HKBN has not created a DNS domain by the name of s2hkbntel.net. As a result, you need to have this entry in order for Asterisk to figure out which host to send your calls to and from which host calls should be accepted.
Please kindly let me know if this provider can be supported or not. Thanks a lot!
