Grandstream GXP 1100, 1400, 1600 and 2100 Series

This guide will help to setup the following Grandstream GXP series phones - 1100, 1400, 1600 and 2100, with your sipgate account.

To configure your Grandstream you will need your SIPID and SIP Password.

Follow the instructions in your device manual login to the Web Configuration Menu of your Grandstream.

Enter the following settings to setup your Grandstream:

 Under Account --> Network Settings set STUN to "Keep Alive". 

We recommend you make the following optional changes:

- Settings --> Call Features: Set the option Disable Direct IP Call to Yes

- Account --> SIP Settings --> Security Settings: Set the options Check SIP User ID for incoming INVITE and Accept Incoming SIP from Proxy Only to Yes.

Testing your Phone's setup:

To test your phone's configuration, dial the following sipgate numbers:

• 10000
• 10005
• 10020

If you have problems registering your Grandstream online or with making calls, test with the STUN Server enabled.

To enable STUN open Account x --> Network Settings and set the option NAT Traversal to STUN.

Using Multiple Phones Behind the Same Router:

If there's more than one VoIP phone/device on the same local network, assigning each different local UDP ports will avoid port conflicts.

For each SIP Phone or device you add, increment the local ports used by 100.
