1.  If the target IP address is 192.168.0.10, the dialing convention is  

Voice Prompt with option 47, then 192 168 000 010 
followed by pressing the “#” key if it is configured as a send key or wait for more than 5 seconds.  

 

2.  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. 

 
NOTE:   When placing a direct IP call, the “Use Random Port” should be set to “NO”. 
 

This function is applicable on the FXS port for VoIP calls only.

 

While in conversation, pressing the “flash” 

button on the connected phone (if the phone has that button) places the remote end on hold. Pressing the 
“flash” button again releases the previously held party and the conversation can resume. If no “flash” 
button is available, then on-off hook quickly (hook flash) will do the same thing.  You may lose the call if 
‘hook flash’ is not quick enough.  
 

This function is applicable on FXS port for VoIP calls only.

 

If the call waiting feature is enabled, the user 

will hear a special stutter tone if there is another call on the line.  Press the flash button to place the 
current party on hold and switch to the other call.  Pressing the flash button toggles between two active 
calls. The HT503 also provides CWCID (call waiting caller ID) information which includes caller ID 
information in addition to the special stutter tone.  The analog phone must support this feature for it to 
work on the HT503.  Both call waiting functions (call waiting and CWCID) are activated and deactivated 
from the configuration pages menu. 

The HT503 supports both blind transfer and attended transfer.
