Note
•
Up to 2 SIP carriers can be connected to simultaneously.
•
Trunks ports 1 through 8 can be allocated to SIP carriers.
•
Each trunk port can be set to a SIP carrier or an analogue line.
•
Both of the WAN ports (WAN1 and WAN2) can be used for either SIP carrier connections (pri-
vate network) or IP network connections (public network).
•
To identify which LAN/WAN port is being used for each SIP carrier when both WAN1 and WAN2
are enabled, the routing information to each SIP Carrier must be retained.
