IP Calls are internal calls sent via an internal data network (LAN or WAN) and the transfer of data and voice is made on the same line. If you are connected to an internal data network the IP connection is made automatically. To minimize the traffic on the network the speech quality is decreased.
If the speech quality is not acceptable you can disconnect the IP Call and switch to a non-IP Call (alternative network). The switch from the IP net to the non-IP net is made during the call, so the call does not have to be disconnected.
If you want to switch to a non-IP net during the call:
Inquiry  |
Press.
   |
Dial.
During the procedure the other party is put on hold. When the procedure is ready you will receive a special ringing tone and the call is resumed in the non-IP net.
A switch to a non-IP Call can only be performed if the original call is an IP Call, otherwise you will receive a Blocking tone.
