5.2 Make Phone Calls
5.2.1 Calling phone or extension numbers
To make a phone or extension number call:
a) Dial the number directly and wait for 4 seconds (default “No Key Entry Timeout”). Or
b) Dial the number directly, and press # (assuming that “Use # as dial key” is selected in web
configuration).
Other functions available during the call are call-waiting/flash, call-transfer, and call-forward.
5.2.2 Direct IP calls
Direct IP calling allows two phones, that is, a HandyTone with an analog phone and another VoIP
Device, to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between
two phones if:
•Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
products) have public IP addresses, or
•Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
produces) are on the same LAN using private or public IP addresses, or
•Both HandyTone ATA and the other VoIP device (i.e., another HandyTone ATA or other SIP
products) can be connected through a router using public or private IP addresses.
To make a direct IP call, first pick up the analog phone or turn on the speakerphone on the analog
phone, follow Section 5.1 with voice prompt 47, followed by the 12-digit target IP address. Destination
ports can be specified by using “*4” (encoding for “:”) followed by the encoded port number.
Following is a table of the encoding scheme for the most commonly used characters:
Input Meaning
00 0
01 1
02 2
03 3
04 4
05 5
06 6
07 7
08 8
09 9
*0 . (dot character)
*4 : (column character)

HandTone-496 User Manual Grandstream Networks, Inc.
11
Examples:
If the target IP address is 192.168.0.160, the dialing convention is
Voice Prompt with option 47, then 192168000160
followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the
default destination port 5060 is used if no port is specified.
If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
Voice Prompt with option 47, then 192168001020*45062 followed by pressing the “#” key if it is
configured as a send key or wait for 4 seconds.
5.2.3 Blind Transfer
Assuming that call party A and B are in conversation. A wants to Blind Transfer B to C:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial
tone.
2. Then A dials *87 then dials C’s number, and then #(or wait for 4 seconds)
3. A can hang up.
Note: Call Feature has to be set to YES.
A can hold on to the phone and wait for one of the three following behaviors:
•A quick confirmation tone (temporarily using the call waiting indication tone) followed by a
dial tone. This indicates the transfer is successful (transferee has received a 200 OK from
transfer target). At this point, A can either hang up or make another call.
•A quick busy tone followed by a restored call (on supported platforms only). This means the
transferee has received a 4xx response for the INVITE and we will try to recover the call. The
busy tone is just to indicate to the transferor that the transfer has failed.
•Busy tone keeps playing. This means we have failed to receive the second NOTIFY from the
transferee and decided to time out. Note: this does not indicate the transfer has been
successful, nor does it indicate the transfer has failed. When transferee is a client that does not
support the second NOTIFY (such as our own earlier firmware), this will be the case. In bad
network scenarios, this could also happen, although the transfer may have been completed
successfully.
5.2.4 Attended Transfer
Assuming that call party A and B are in conversation. A wants to Attend Transfer B to C:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone
2. A then dial C’s number then # (or wait for 4 seconds). A and C now in conversation.
3. A can hang up.

HandTone-496 User Manual Grandstream Networks, Inc.
12
Note: When intended Transfer failed, if A hangs up, the HandTone-496 will ring user A again to
remind A that B is still on the call, by pressing FLASH or Hook again will restore the conversation
between A and B.
