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.
NOTE: When Attended Transfer fails and A hangs up, the GXW400X will ring back user A to remind A
that B is still on the call. A can pick up the phone to resume conversation with B.
3-WAY CONFERENCING
The GXW400X supports Bellcore style 3-way Conference.
Instructions for 3-way conference:
Assuming that call party A and B are in conversation. A (GXW400X) wants to bring C in a 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, C in 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 conference, C will be dropped out.
6. If A hangs up, the conference will be terminated for all three parties when configuration
“Transfer on Conference Hangup” is set to “No”. If the configuration is set to “Yes”, A will
transfer B to C so that B and C can continue the conversation.
HUNTING GROUP
This feature allows the user to setup a single SIP account on the gateway and have the ability to use all
FXS ports to make/receive calls. Using this feature, all ports active in same Hunting Group will have the
same phone number and incoming calls will be distributed in a Linear or Circular manner among the ports
active in that Hunting Group. The number of hunting groups is limited by the number of ports each GXW
model has - i.e. each port can be its own Hunting Group. The most practical and efficient way to use
Hunting Groups is to assign 2 or 3 ports to separate Hunting Groups.
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 4008 ports
