Please refer to the GUI pages using the following link:
http://www.grandstream.com/products/dp_series/dp71x/documents/dp715_gui.zip .
Note: If you cannot log into the configuration page by using the default password, please check with the
VoIP service provider. It is most likely the VoIP service provider has provisioned the device and configured
for you therefore the password has already been changed.
IMPORTANT SETTINGS
The end-user must configure the following settings according to the local environment.
Note: Most settings on the web configuration pages are set to the default values.
NAT Settings
If you plan to keep the DP715 Base Station within a private network behind a firewall, we recommend using
STUN Server. The following three (3) settings are useful in the STUN Server scenario:
1. STUN Server (under Advanced Settings webpage)
Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the
internet and enter it on this field. If using Public IP, keep this field blank.
2. Use Random Ports (under Advanced Settings webpage)
This setting depends on your network settings. Generally if you have multiple IP devices under the
same network, it should be set to Yes. If using a Public IP address, set this parameter to No.
3. NAT Traversal (under the Profile web page)
Set this to Yes when gateway is behind firewall on a private network.
DTMF Methods
DTMF Settings are in ProfileX page.
 DTMF in-audio
 DTMF via RTP (RFC2833)
 DTMF via SIP INFO
Set priority of DTMF methods according to your preference. This setting should be based on your server
DTMF setting.

 G711a/u
