Technical Specifications

Hardware Specifications

To enter the voice prompt menu on the GRANDSTREAM NETWORKS HT503, press *** from the analog phone connected to the FXS port. The voice prompt menu is designed for the FXS port only.

NOTE:

• “*” shifts down to the next menu option.

• “#” returns to the main menu.

• “9” functions as the ENTER key in many cases to confirm an option.

• All entered digit sequences have known lengths – 2 digits for menu option. For IP address, the “*” key represents the dot “.” (e.g., 192.168.0.26 should be keyed in as 192*168*0*26). Once all of the digits are collected, the input will be processed.

• Key entry cannot be deleted but the phone may prompt error once it is detected.

There are two methods to make an extension number call with the GRANDSTREAM NETWORKS HT503:

a) Dial the numbers directly and wait for 4 (default) seconds.

b) Dial the numbers directly, and press # (assuming that “use # as dial key” is selected in the web configuration).

Examples:

• To dial another extension on the same proxy, such as 1008, simply pick up the attached phone, dial 1008 and then press the # or wait for 4 seconds.

• To dial a PSTN number such as 6266667890, you may need a prefix number followed by the phone number. Please check with your VoIP service provider for this information. If your phone is assigned a PSTN-like number such as 6265556789, you will most likely follow the rule 1 + (the number) – 16266667890. Press # or wait for 4 seconds.

Direct IP calling allows two parties (an FXS Port with an analog phone and another VoIP Device) to talk to each other without a SIP proxy. The GRANDSTREAM NETWORKS HT503 supports two ways to make Direct IP Calls:

Using IVR

1. Pick up the analog phone then access the voice menu prompt by dialing “***”.

2. Dial “47” to access the direct IP call menu.

3. Enter the IP address using format ex. 192*168*0*160 after the dial tone.

Using Star Code

1. Pick up the analog phone then dial “*47”.

2. Enter the target IP address using the same format as above. Note: NO dial tone will be played between step 1 and 2.

Destination ports can be specified by using “*” (encoding for “:”) followed by the port number. For example, to call 192.168.1.20:5062, you would dial *47 then 192*168*0*160*5062.

NOTE: When completing a direct IP call, the “Use Random Port” should be set to “NO”.

CALL HOLD

This function is applicable on the FXS port for VoIP calls only. While in conversation, pressing the “flash” button on the connected phone places the remote end on hold. Pressing the “flash” button again releases the previously held party and the conversation can resume. If no “flash” button is available, then on-off hook quickly (hook flash) will do the same thing.

CALL WAITING

This function is applicable on the FXS port for VoIP calls only. If the call waiting feature is enabled, you will hear a special stutter tone if there is another call on the line. Press the flash button to place the current party on hold and switch to the other call. Pressing the flash button toggles between two active calls.

CALL TRANSFER

The GRANDSTREAM NETWORKS HT503 supports both blind and attended transfer for VoIP calls on the FXS port.

Blind Transfer:

Assume Party A is in conversation with Party B, and wants to transfer B to C.

1. A presses FLASH on the analog phone to hear the dial tone.

2. Then A dials *87, then dials C’s number, and then presses #.

3. A can hang up.

NOTE: “Enable Call Feature” must be set to “Yes” in the web configuration page.

Attended Transfer:

Assume Party A is in conversation with Party B, and wants to transfer B to C.

1. A presses FLASH on the analog phone to get a dial tone.

2. A then dials C’s number followed by #.

3. If C answers the call, A and C are in conversation. Then A can hang up to complete the transfer.

4. If C does not answer the call, A can press “flash” back to talk to B.

Assume parties A (using the HT503) and B are in conversation, and A wants to bring C into a 3-way conference:

1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.

2. A dials C’s number then # (or wait for 4 seconds).

3. If C answers the call, then A presses FLASH to bring B and C into the conference.

4. If C does not answer the call, A can press FLASH back to talk to B.

5. If A presses FLASH during the conference, C will be dropped.

6. If A hangs up, the conference will be terminated for all three parties if “Transfer on Conference Hangup” is set to “No”. If set to “Yes”, A will transfer B to C so they can continue the conversation.

The GRANDSTREAM NETWORKS HT503 supports PSTN pass through using the FXS port, allowing you to place and receive PSTN calls with an analog phone connected to the FXS port.

• To receive PSTN calls, pick up the phone when it rings.

• To make a PSTN call, press the PSTN access code (*00 is default, or any number configured in the web configuration) to switch to the PSTN line, listen for a dial tone, then dial the number.

• If the HT503 loses power or registration with the SIP server, the device will switch to a mode where the PSTN line is transparently connected directly to the phone on the FXS port, enabling a direct connection to the PSTN Line.

The FXO port on the GRANDSTREAM NETWORKS HT503 functions as a bridge between the Internet and PSTN. To make a VoIP-to-PSTN call:

1. Dial the FXO SIP account phone number to establish the VoIP session. You will hear the ring back tone once, followed by either a special continuous tone (if a PIN is configured) or a dial tone.

2. Enter the PIN code (if configured). If the PIN is valid, you will hear a dial tone and be connected to the PSTN line. You may try up to 3 times to enter a correct PIN.

3. After hearing the dial tone from the PSTN line, you can place the next call.

4. You can hit the # key to identify the end of the PIN code or wait 4 seconds for a new dial tone before dialing the PSTN number.

The FXO port on the GRANDSTREAM NETWORKS HT503 enables calls to be passed from the PSTN network to VoIP. To make a PSTN-to-VoIP call:

1. Make an incoming call to the PSTN line on the FXO port. The phone will ring for 4 times by default (this is configurable).

2. If no one answers the call after 4 rings, you will hear either a special continuous tone (prompting for a PIN) or a dial tone.

3. Enter a valid PIN (if configured). You will hear a dial tone and be bridged to VoIP. If the PIN is incorrect, you can try up to 3 times.

4. Dial a VoIP number followed by # (or wait for 4 seconds); the VoIP call will be initiated from the SIP account configured on the FXO port.

The GRANDSTREAM NETWORKS HT503 HTML configuration page can be accessed via LAN or WAN ports.

From the LAN port:

1. Directly connect a computer to the LAN port.

2. Open a command window on the computer.

3. Type in “ipconfig /release”.

4. Type in “ipconfig /renew”; the computer gets an IP address in the 192.168.2.x segment by default.

5. Open a web browser and type in the default IP address of the LAN port: http://192.168.2.1. You will see the log in page of the device.

From the WAN port:

1. Find the WAN side IP address using the voice prompt menu (option 02).

2. Open a web browser and type in the WAN side IP address.

Note: WAN side HTTP access is disabled by default. You can enable it on the configuration page by setting “WAN side HTTP access” to YES.
