Thank you for purchasing the Grandstream GXE502X IP-PBX, a SIP-based, affordable,
feature-enriched converging communication platform designed to meet the communication
requirements for small to medium sized enterprises.
The GXE502X provides the cutting-edge IP-based communications that businesses demand
while leveraging existing infrastructure and providing a smooth transition into IP telephony.
Based on open-standard SIP, the GXE502X can easily integrate into and interoperate with
other components of your existing communications network while providing a rich set of
features to reduce costs and increase productivity. Built-in FXO and FXS ports enable the
GXE502X to interface with analog lines and devices while concurrently registering to SIP
trunks and SIP-based trunk gateways to maximize available communications resources. The
PoE capability (LAN port) and low power consumption (15Watt Max.) solidify the GXE as an
environment friendly solution (compared to similar PC based systems). This also ensures nonstop communication even during power outages (necessary UPS required)
The GXE502X also includes an Express Setup wizard and an intuitive user interface that
allows users to quickly configure extensions. Voicemail, fax mail, faxmail-to-email, conference
bridges and other enhanced features can be turned on with minimal effort via the GXE502X
web configuration interface. The GXE’s broad feature set, ease of operation and affordable
price range make it ideal for any SMB.
•Equipment Packaging
The GXE502X IP-PBX package contains:
1) One GXE502X IP-PBX unit
2) One 12 Volt power adapter
3) One Ethernet cable
2. Extension Configuration
Phone Extensions
The front end menu of the GXE web interface is the Phone Extensions menu. This menu and
it’s several different sub menus allow users to configure and add extensions with ease.
Extensions for internal users can be created from the Express Setup menu of a factorydefault GXE502X or from the Phone Extensions menu at any time. The extensions can be
local users (shown in Green in the Extensions Directory) in the internal network, or remote
users connecting over the open Internet (shown in Blue in the Extensions Directory). This
flexibility allows GXE502X users to bring their office extensions virtually anywhere that has a
broadband Internet connection. This gives users easy access to personnel (home office and
road warriors alike) without incurring any PSTN toll charges.

GXE502X User Manual 7/9/2008
The FXO and FXS port/line electric specification parameters and settings can be configured in
this area as well. All of these will allow users of the GXE502X to make calls anywhere through
multiple trunk types.
- Internal PSTN Trunk Line Configuration (via FXO ports)
The Internal PSTN Trunk Line Configuraiton page lets your configure the FXO ports on the
back of the GXE502X to make and receive calls to and from the PSTN.
Compatibility with different PSTN lines can be achieved by adjusting the related parameters on
the Internal PSTN Trunk Line Configuration page. The default settings should function in most
cases. Correct technical data must be obtained from local Telco carriers and implemented on
the GXE502X before the lines will function. This data depends on the regional PSTN line
characteristics.
FXO Termination:
impedance.
•Enable Current Disconnect: Default is Yes.
Version 03
This section lets you specify the line disconnect signaling and
8
GXE502X User Manual 7/9/2008
This value should be used when the PSTN provider or local Telco Carries uses a line
power drop to indicate call completion to the subscribing end point. In this case the FXO
port of GXE502X will search for a power drop with the preconfigured time frame to
disconnect call from a VoIP extension.
•Current Disconnect Threshold:
This is a preconfigured value of duration for a line power drop used by specific service
providers or Telco Carriers. For example, with a configured value of 500ms, the device
will ignore any random voltage drops on the line if the duration of such a drop is less
than 500ms. The call will NOT be considered as terminated, but will clear a call if a drop
is equal or more than 500ms. This is useful to prevent unnecessary call drops in some
low quality PSTN lines. However inappropriate parameters may cause calls to drop
unexpectedly or cause the line not to release as expected. Please consult with the local
Telco carrier before change this parameter.
•Enable Tone Disconnect:
This feature causes a Busy Tone to be used as the FXO line disconnection signal when
set to YES. Used by some Telcos or enterprise POT PBX.
•Polarity Reversal Disconnect:
If set to “Yes”, calls will be terminated after a polarity signal reversal. The default value
is No.
•AC Terminal Impedance Scheme:
Users can select one of two options for the AC termination scheme: Country (rough
and easy) or t h e Model of related Impedance values (real and complex).
Please make note that inappropriate parameters may cause echo or popping noises on
the lines.
Please consult with your local Telco Carrier before configuring these fields.
•AC Terminal Impedance:
This depends on whether Country or Model is selected, either 15 Countries are
selectable or users have to select the Impedance value used by the local PSTN carriers
Call Progress Tones: This feature lets you configure tones to match the FXO line
regional settings.
In certain countries, the carriers or central office will send special tones to indicate certain
events on the PSTN side. For example, when a call is disconnected from the remote side
the other side will hear a busy tone indicating that the call is terminated. Also, a dial-tone is
used by the central office to signal that it is ready to receive digits and process the call.
Users can pre-configure these tones in the GXE502X. However users must know the
correct frequency values and cadences of these tones from the PSTN carrier. Wrong
parameters may cause the GXE502X to malfunction due to incorrect tone settings.
Here is an example for the syntax for a busy tone in the U.S.A:
Default US Busy Tone: f1=480@-24,f2=620@-24,c=500/500)
Line Dialing Settings:
PSTN line requirements.
•DTMF Digit Length: The DTMFDigit Length is the play time of DTMF in milliseconds
for each digit dialing out from the VOIP side to PSTN
• DTMF Digit Volume: The digit output power in dBm.
• DTMF Dial Pause: Dial pause is the time between 2 digits when dialing out through the
PSTN.
•Wait for Dial-Tone: If set to Yes, the device will first obtain a PSTN line and wait for a
dial tone from the central office. After obtaining the dial tone, the digits dialed will be
sent to the central office.
•Minimum Delay Before Dial: This parameter lets users configure a variable delay
before dialing the first digit into the PSTN.
This feature adjusts line dialing properties to adhere to the
Caller ID Standard: This feature configures caller ID handling to match local PSTN
settings.
•Caller ID scheme: This feature lets youselect the model used by local PSTN provider.
Please check with local PSTN carrier for configuration information. Current supporting
including: Bellcore, ETSI, DTMF or NTT
•FSK Caller ID Minimum RX Level: This is an adjustable threshold value for the Caller
ID signal strength received to help the device to recognize Caller ID from different
networks. (-96 -0dB. Default -40dB)

o Trunk Active: Set to Enable to activate the SIP trunk to be configured.
o Outgoing Call Password Protection: If configured to Yes, a password is required
whenever calling out on the trunk. The default setting is No.
oSIP Server URL: The SIP server IP or URL provided by your SIP trunk service
provider.
oOutbound Proxy UR L: The Outbound Proxy or Session Border Controller IP or URL
provided by the SIP trunk service provider.
o Account Name: Lets you specify a name to identify the SIP trunk service provider.
o Account ID: The Account ID provided by your service provider, usually the VoIP
line/trunk number.
oAuthenticate ID: The Authenticate ID used by your VoIP or SIP trunk service
provider.
o Password: The password of the account provided by your service provider.
o Registration Retry Interval: The expiration time interval for the GXE502X to retry or
update registration. This is usually regulated by SIP server configured here.
Reducing this time interval will keep registration more synchronized with the SIP
server but with the cost of more registration packets sent to server. The default
value is 600 seconds or 10 minutes.
oHeart Beat: if set to Yes, the GXE502X will send a SIP OPTIONS Request
frequently to check whether the SIP Proxy is still online. If the Proxy does not
support by answering with a SIP 200 OK then the GXE502X will consider this trunk
as disconnected. This feature is also used to keep a UDP port open when the
GXE502X is behind a NAT firewall.
oMax. Concurrent Calls Allowed: The maximum number of concurrent calls allowed
by your SIP trunk service provider. This depends on whether dynamic or static SIP
trunks are used. The number can range from 2 to numbers limited only by available
bandwidth of the physical link pipe.
oDial Prefix: Sets the Dial Prefix digit(s) required to make an outbound call through
this trunk. When the call is sent out via this trunk, the dial prefix digits will be
removed.
oPrepend Prefix: This field allows a prefix to be automatically added by the GXE502X
to the outbound dialing digits. For example, if the SIP trunk service provider requires
a “+” for all outgoing calls to be E.164 compatible, then input “+” here in this field.
oInbound Call Answer: This field lets your set the destination where incoming calls
are terminated on this trunk. Callsl can be terminated into the Auto-Attendant (IVR),
direct extensions, hunting/ring group or the conference bridge(s).

GXE502X User Manual 7/9/2008
oSession Keep Alive: This field allows users to enable or disable usage of the session
timer. This is enabled by default to: Automatic/Session Timer.
oSession Expiration: The session timer enables SIP sessions to be periodically
“refreshed” via a SIP request. If enabled, before the session interval expires, the
GXE502X will send a SIP re-INVITE message to the SIP server, if this message is
not replied the session will be terminated. This will avoid stalled sessions occupying
the channel/bandwidth. Session Expiration is the timer (in seconds) at which the
session is considered timed out if no successful session refresh transaction occurs
beforehand. The default value is 180 seconds. Incorrect configurations could cause
calls to get dropped.
oMin-SE: The minimum session expiration (in seconds). The default value is 90
seconds.
oUse DNS SRV: Default is No. Select “Yes” if the domain name of the SIP server or
Outbound Proxy is compliant with RFC2782. The SIP trunk will not function properly
if this field is not configured correctly.
oUnregister on Reboot: Default is No. If set to “Yes”, The GXE502X will first send a
registration request to remove all previous or multiple bindings by adding “*” in the
SIP Contact Header. Please use this feature ONLY if the proxy supports removal
binding requests. Otherwise the SIP trunk will not function properly.
oRegister Active: This parameter controls whether the GXE502X needs to send
REGISTER messages to the Proxy Server before making or receiving calls. The
default setting is “Yes” (for most dynamic SIP trunks).
Note:
For security reasons: If this is set to “No” (for most static SIP trunks) any incoming
request MUST match the SIP server IP or the FQDN resolution must match the
sending IP address.
oCBCOM Encryption: If set to Yes, RTP will be encrypted as per the algorithms of
CBCOM. The Default setting is No.
oDID Switch: This field is used to route incoming calls when a DID (Direct Inward
Dialing #) is used instead of the account ID. It is very helpful when there are several
DIDs related to the same (static) trunk provided by your SIP Trunk Service Provider.
Note:
All SIP requests are verified by the GXE502X so the User Part of the SIP URI has to
match the account ID or the DIDs. For outgoing calls when DID switch is enabled,
the DID number in the list will be used in the From, Contact and PAI (P-AssertedIdentity) value.
If a prepend prefix is configured, it will also be used as prefix for the DIDs.
For example, if the DID is +16175669300 and for outgoing calls the service provider
requires “+”, then configure the prepend prefix to “+” and add the DID 16175669300.
Then +16175669300 will be used to match both incoming calls and also outgoing
calls.
