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 dials C’s number then # (or wait for 4 seconds).  A and C are now in conversation. 
3.  A can hang up.
