DIRECT IP CALLS

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to
talk to each other in an ad hoc fashion without a SIP proxy.
Elements necessary to completing a Direct IP Call:
1. Both HT502 and other VoIP Device, have public IP addresses, or
2. Both HT502 and other VoIP Device are on the same LAN using private IP addresses, or
3. Both HT502 and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).

Using IVR
1. Pick up the analog phone then access the voice menu prompt by dial "***"
2. Dial "47" to access the direct IP call menu
3. Enter the IP address after the dial tone and voice prompt "Direct IP Calling"
Using Star Code
1. Pick up the analog phone then dial "*47"
2. Enter the target IP address.
Note: NO dial tone will be played between step 1 and 2.
