Q: Can you peer multiple GXEs through DDNS as oppose to using a static IP address?
Yes, it is possible to use a dynamic domain name. However the current firmware does not
support TZO so if the IP address changes the GXE does not have the client to update it.
Q: Can you prepend an area code as a prefix on the FXO ports for outgoing calls?
No, at this time you can only put a prepend prefix on SIP trunks.
Q: When entering the voicemail system my extension # and password are not recognized by
the GXE. How can I fix this?
The GXE502X uses RFC 2833 for its DTMF tones. Make sure that all registered SIP devices
have their DTMF mode set to RFC 2833.
Q: When I enter the voicemail feature code: *99 I do not hear an IVR? What can I do?
Your GXE may not have come pre-loaded with the newest voice prompts. Click here to
download the newest voice prompts.
Q: Why doesn't anything happen when I try to dial in or out of my PSTN lines?
Most likely you did not set up the line call control for the FXO port that the PSTN line is
connected to. Click on the Trunk/Phone Lines section of the web UI and go to the Internal PSTN
Trunk Line configuration page. Go to the Line Call Control field at the bottom the page and set
up the outbound prefix and inbound call flow for each FXO port that is connected to a phone
line. Save your changes and reboot the GXE. Your analog phone lines should now work
properly.
Q: Why I can not read the PDF file for FAX?
You will need to upgrade Adobe-Read software to V6.0 or V7.0. The PDF file generated for
GXE5000 cannot be opened with Adobe-Read V2.0.
Q: How does feature code work?
Feature code is pretty much self-explanatory, to use * code, make sure put a * after the feature
code., e.g, feature code *72 is * code for "Unconditional Call Forward", if you want to enable it
for extension 8003, then the dial sequence should be: *72*8002.
