18. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Conference Calling To turn a 2-party call into a 3-party call: Press flash and wait for recall tone. Dial the desired number and listen for ring back tone. Wait for the party to answer, consult, then flash to complete the conference.

19. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Transferring a Call To transfer a call: 1.Press flash and wait for recall tone. 2.Dial the desired number. 3.Listen for ring back tone and. a)To transfer immediately, simply hang up; Or. b)To transfer with consultation, wait for the party to answer, consult, then hang up.

20. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Call Waiting If you are enabled for call waiting and hear the call waiting tone, press flash to answer the second call. The first call will be put on hold. To return to the first call, without hanging up on the second call, press flash again. The second call is put on hold and you are connected to the first call. When finished with either call, you may hang up and press flash to return to the other call.

21. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Forward to Another Extension Pickup an extension, dial 42, followed by the extension you want to forward. To cancel forward, just pickup the extension, dial 44.

22. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Pickup Another Extension To pickup any ringing extension, dial *13, followed by the extension you want to pick up, or followed by * that mean current ringing extension.

23. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Putting a Call on Hold To put a call on hold, press flash. You can dial another number or even hang up. To return to the original call, simply press flash.

24. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 Don ’ t Disturb Pickup an extension, dial 51 To cancel, just pickup the extension, dial 52

25. Beijing Embedded System Key Lab 北京嵌入式系统重点实验室 5 Home Work Read the Block Diagram of VoIP HW&SW architecture and remember them. Read the chips’ data sheet on the VoIP board, remember their main features. Try to run the VoIP board and try the basic and special calling functions.
