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 for more than 5 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 5 seconds.
Currently, we don’t support inter-domain IP to IP call like:
5.2.3
Blind Transfer
Assume 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.
NOTES:
• Call Feature has to be set to YES in web configuration page.
A can hold on to the phone and await one of the three following behaviors:
• A quick confirmation tone (temporarily using the call waiting indication tone) follows by a
dial tone. This indicates the transfer has been successful (transferee has received a 200 OK
from transfer target). At this point, you 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 decide 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, this will be the case. In bad network scenarios, this could also happen,
although the transfer may have been completed successfully.
