RE: SIP-T20P: Register Failedand and no Call
Dear Daniel,

I have progress on VPN but believed that setting up the modem or access router , opening port 1723 for VPN connection, could connect at least one phone in each branch .
I have to test :

1 computer on my local network that would be the client.
I set up a VPN connection with public IP. Setup:
Login : sylvio
Password: xxx
I visit the " yougetsignal " and tested the port 1723 (server). It´s open . I got the server remote address "".

1 computer ( server ) connected to ADSL ( GVT in Brazil , only for testing ) ,
DHCP: to
Modem opening port 1723
Port forwarding port 1723 to ip PC (router)
DMZ off
DDNS off

Router simulating a server:
Router IP :
DHCP: range to 199
Virtual Server List :
Name: VPN
Application: PPTP
Port : 1723
Protocol: TCP
IP :

Config the input connection to VPN (server)
Login : sylvio (administrator)
Password: xxx
IP range to 199 .

error 800 the remote connection was not made ​​because the attempted vpn tunnels failed

If I can not solve this not be able to install the phones.

Please help me ,
