NOTE: When Attended Transfer fails and A hangs up, the HT802 will ring back user A to remind A that B

3-WAY CONFERENCING

The HT802 supports Bellcore style 3-way Conference.
Instructions for 3-way conference:
Assume that call party A and B are in conversation. Caller A(HT802) wants to bring third Caller C into
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.

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 Hang up" 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.

FAX SUPPORT

HT802 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. If the service provider
supports T.38, please use this method by selecting Fax mode to be T.38 (default). If the service provider
does not support T.38, pass-through mode can be used.
