• Normally, SIP From URI will contain the Extension's calling ID and ePBX's IP
address, but some ITSP may reject this cal due to some security issue. You can
modify the Calling ID and IP/ Domain in the fields of [External Server Address] and
[Outbound Caller ID] when the cal is going via the ePBX to the Destination (Trunk)
to avoid such security issue.
• If you set a Dynamix DW FXO gateway as the Trunk, you can just use the default
Trunk 888 and 889 as the FXO's register number.
• For the FXO gateway, you may just configure Extension Number, Password, Host:
Dial Plan, Keypad, NAT Traversal and RTP Mode.
• If you set the ITSP as the Trunk, you may need to set the following configure: Port,
External Server Address and Outbound Caller ID.
• For more information, please refer to the Appendix A: Application between
Dynamix DW CPE device and e P B X - 1 .
