•  Once the button is pressed, it enters the voice prompt main menu. If the button is pressed again, 

•  “*” shifts down to the next menu option 

•  “#” returns to the main menu 

•  “9” functions as the ENTER key in many cases to confirm an option 
•  All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP 

•  Key entry can not be deleted but the phone may prompt error once it is detected 
 

 
 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). 

 
Examples: 
 

To dial another extension on the same proxy, such as 1008, simply pick up the attached phone, 

dial 1008 and then press the # or wait for 4 seconds.  
 

To dial a PSTN number such as 6266667890, you might need to enter in some prefix number 

followed by the phone number. Please check with your VoIP service provider to get the information. If 
you phone is assigned with a PSTN-like number such as 6265556789, most likely you just follow the 
rule to dial 16266667890 as if you were calling from a regular analog phone, followed by pressing  # 
or wait for 4 seconds.  
 

 
Direct IP calling allows two parties, 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. This kind of VoIP calls can be 
made between two parties if: 
 

•  Both HandyTone ATA and other VoIP Device(i.e., another HandyTone ATA or Budgetone SIP 

phone or other VoIP unit) have public IP addresses, or  

•  Both HandyTone ATA and other VoIP Device are on the same LAN using private IP addresses, 

or  

•  Both HandyTone ATA and other VoIP Device can be connected through a router using public 

or private IP addresses (with necessary port forwarding or DMZ).
