FIGURE 3: LCD MENU FIRMWARE 1.0.3.
BASIC OPERATIONS UNDERSTANDING GXW VOICE PROMPTS GXW4248 has a built-in voice prompt menu for simple device configuration. To enter the voice prompt menu, press *** on the standard analog phone connected to any FXS port.
“9” to toggle between TFTP and HTTP 016 Firmware Version Firmware version information. 017 Firmware Upgrade Firmware upgrade mode. Enter “9” to rotate among the following three options: 047 “Direct IP Calling” 1. always check 2. check when pre/suffix changes 3. never upgrade Enter the target IP address to make a direct IP call, after dial tone. (See “Make a Direct IP Call”.
Examples: 1. Dial a number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers. DIRECT IP CALLS Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy. Elements necessary to completing a Direct IP Call: 1.
*47 or Voice Prompt with option 047, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds. CALL HOLD Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button). Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash” button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.
ATTENDED TRANSFER Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C: 1. Caller A presses FLASH on the analog phone for dial tone. 2. Caller A then dials Caller C’s number followed by # (or wait for 4 seconds). 3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to complete transfer. 4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.
One additional and popular way to use the Hunting Group feature is called “multiplexed analog lines”. In this configuration, a legacy PBX system with 8 FXO trunks can be connected to 8 GXW 42xx ports configured as a Hunting Group. The GXW can be registered to a SIP server provider using only one phone number. If the SIP service provider allows multiple calls to the same number, the GXW will allow 8 concurrent calls to the same SIP number.
8 is required to indicate that the SIP account tied to port marked as “Active” will be used for all members of the same Hunting group. Needless to say, those members of the same Hunting group may not be sequential ports. In following example ports 3, 5 and 7 tied to SIP Account configured in Port #1 marked as “Active”, and ports 4,6,8 tied to SIP Account configured in Port #2 marked as “Active” as well.
For example, on the GXW4248 inter-port calling is achieved by dialing *** and 7 plus two extra digits corresponding to the port number. For example the user connected to port 1 can be reached by dialing *** and 701; the user connected to port 24 can be reached by dialing *** 724. SENDING AND RECEIVING FAX GXW4248 supports fax in two modes: 1) T.38 (Fax over IP) and 2) Fax Pass through. T.38 is the preferred method because it is more reliable and works well in most network conditions.
CALL FEATURES GXW4248 supports the traditional telephony features available in a PBX as well as additional advanced telephony features. TABLE 6: CALL FEATURES TABLE (STAR CODE) Key Call Features *02 Forcing a Codec (per call) *027110 (PCMU), *027111 (PCMA), *02723 (G723), *02729 (G729), *0272616 (G726-r16), *0272624 (G724-r24), *0272632 (G726-r32), *0272640 (G726r40), *027201 (iLBC) *03 Disable LEC (pe call) Dial “*03” + ” number ”. No dial tone is played in the middle.
