Remote Phone Support
Remote Working - NAT Traversal
The new Remote Worker feature allows the connection of remote 9600 Series IP Telephones with the H.323 FW
which resides behind a NAT Router to IP Office Release 8.0 and later. The configuration does not require any
VPN concentrator equipment with the IP Office system.
With the Remote Worker feature enabled, remote 9600 H.323 IP Phones can connect to the IP Office system
even if the IP Office is located behind a NAT router. The sets are authenticated on the IP Office in the same way
as sets in the private network. The IP Office will determine that a set is located outside the private network
based and relay the VOIP RTP traffic to ensure it transverses the NAT router.
It is important to note that the H.323 signaling and the media traffic is not encrypted, but the proprietary
binary format adds a basic level of encryption.
To reach the IP Office from the remote private network remote H.323 IP Phone needs to be configured to the
public IP address of the NAT router hosting the IP Office. Configurable ports need to be forwarded to the IP
Office. The IP Office requires a valid public IP address be configured for the feature to function. The public IP
address can be statically configured or dynamically discovered via a STUN server.
The Remote Working feature needs to be enabled in the IP Office Manager. The Remote Worker feature
requires the Essential Edition license which provides four (4) remote worker seats with the IP Office system.
Additional remote worker capability is available with the Teleworker User package and a Preferred Edition
license.
