Comments
333Nice unit, supports IAX2 but:
Port 80 and 23 are open on the WAN and LAN side. It is not possible to disable login from the WAN (Internet), so basically all who purchase this unit and try to rely on it's NAT capability to protect their network will be in for a big surprise.
I think accessing the configuration from WAN is a serious security issue, anybody with a password cracker or sniffer can hack it's password from the Internet without many problems compromising the unit.
I don't know what the customer segment is for this device.
If it is for small businesses, the PSTN line will not register to Asterisk (it is not an FXO) so this line cannot be used with PBX.
If this unit is for your family members abroad, it would be a nice unit if not for the open ports on the WAN side. Configuration should only be accessible from the LAN side or at least give the user the ability to disable the WAN login.
With the current setting the unit can be cracked within minutes.
2.) Half of the people who buy this product will not change the default password "user: admin, password: admin" as they they will think that they are protected by it's NAT configuration and they will be in for a big surprise.
3.) I just noticed that the LAN section of the device does not allow you to assign "static IP's", this is severe limitation. If I run printers and computers in a small business or at home, but if I access based on the static IP and plug them into the wrong order I think that they will obtain different IP addresses.
4.) The MW (Message Waiting) indicator is not working with this device over IAX2/SIP.
