Call transfers Call transfer is NOT possible between different accounts - in case you will try, you will be prompted and current call will remain untransferred. Calls between the same accounts are possible as before. Incoming calls When an incoming call is ringing, once answered it will toggle the answering line to the incoming account from. This apply also to the answering popup. Redialing by call list and phonebook Each contact in the call history and phonebook "knows" the account where it comes from. Therefore, it will automatically toggle to required account when dialled. In these lists are available only active accounts, not all defined. about BLFs There are two type of BLFs - those named BLF/Xfer and those named Speed dials. The essential difference between them is that BLF/Xfers can be "presenced" by the specified assigned account, while Speed dials cannot. Therefore, a BLF/XFer cannot be assigned to "any" account, while the Speed dial can. Regardless, making calls and blind/attended transfers can be performed by both types of BLFs. The "Any" term means the active account. Supposing your phone has Malta account on Line 1 and Cyprus account on Line2, by pressing the any Speed dial 999 on Line 1 will dial this number on Malta, while on Line2 - on Cyprus. If this BLF - regardless its type - would be assigned to Malta, when it will be pressed on Cyprus line, it will automatically switch that line to Malta then dial. AM/PM clock – click to change to 24hr You may toggle desired format by clicking the clock. Currrent format will be saved in the phone's configuration file. Automatic Direct SiP call when @ is present in dialed uri Until now, to make a direct sip call, it was required to type sip:aaa@bbb. Starting from this version, the presence of the @ character is considered as a strong hint a direct SIP call is desired, so it will enough to type only aaa@bbb - obviously, the sip: format has been preserved.
