Enabling Static NAT Feature for SIP Protocol(SIP Account and SIP IP Call)
If you want to make private-to-public calls via SIP protocol (SIP account and SIP IP call), you need enable
static NAT feature for SIP protocol.
Procedure
1. Do one of the following:
• On your web user interface, go to Account > SIP Account/SIP IP Call > NAT Traversal.
• On your VCS, go to More > Setting > Advanced > SIP IP Call Out > NAT Traversal.
On your VP59, tap Setting > Advanced > SIP IP Call > NAT Traversal.
• On your CTP20, tap Setting > Advanced > SIP IP Call Out > NAT Traversal.
2. Configure and save the following settings:

About this task
In the Intranet, if there is a secondary router connected to the first router, the VCS connected to each router
may not be able to communicate properly. In this situation, you can configure static NAT and enforce the
route traversal feature for the VCS connected to the secondary router, so that the NAT works even though
both devices are in the Intranet.
Attention:
If you enable the route traversal feature forcibly for the VCS connected to the secondary router, the
VCS may fail to call other VCS connected to the same router, because the NAT address replaces the
private address.
Procedure
1. Do one of the following:
• On your web user interface, go to Network > NAT/Firewall > NAT Configuration.
• On your VCS:
On your VC880/VC800/VC500/PVT980/PVT950, go to More > Setting > Advanced > NAT/Firewall
> NAT.
On your VC200, go to More > Network > Wired Network > NAT/Firewall > NAT.
On your VP59, tap Setting > Advanced > NAT/Firewall > NAT.
• On your CTP20, tap Setting > Advanced > NAT/Firewall > NAT.
