Transfer a PSTN telephone landline through a wireless link or a remote local area point.

By using two Grandstream HT813 devices or one Grandstream HT813 with HT801/802 in Client-Server operation we can achieve the transfer of the phone line.

The first step is registering our devices to the local network, we have to assign static Ip to the WAN interface (ex 192.168.x.x)

When we connect WAN port to our network, the device gets automatic address.    

With a simple analog phone device connected on one of the phone ports (green frame), we can access the menu of the device by dialing *** 

By pressing 12 and 9 we activate\de-activate WAN Interface

By pressing 02 we listen the to the given IP address

Assigning Static Ip's to the devices

We are going to the Basic Settings Tab

Στην ενοτητα IPv4 Address και διαλεγουμε την επιλογη statically configured as

Into the Ipv4 Address Section we select statically configured as

and we give the IP we want (ex 192.168.1.200 the Server - 192.168.1.201 the Client).

Configuring Server (ex 192.168.1.200)

-              Primary Sip Port:192.168.1.201 //Set to IP address of Client

-              Sip User ID: 500 //Whatever number we want

-              Authentication ID:500 ///Whatever number we want

-              Ath pass:12345
