Welcome
Congratulations tothe purchaseofVoIPvideo/audiodoorentry phone station
IPBell. Thisdoorphone can meetyourrequirementsforcommunicationswith
visitorsatthe doorentranceofyourhouse,companyorbuilding.The meaning
ofVoIPis“Voice over InternetProtocol”–thisdoorphone can be connected
tothe computernetwork enabling callsinmode P2P(peertopeer) –that
meansitcallstothe IPaddressofotherVoIPequipmentdirectlyoritcan
registertothe SIPserver,then itcan calltophone numbers.Eachpushbutton
can storetwo25 digitnumbersincluding charactersstar“*”and hash“ # ”.
The basicmoduleofthe doorphone issupplied withone ortwo
pushbuttons, inaudioversion orvideo version withacolourcamera.
The IPBell doorphone can be powered eitherby12Vpowersupplywhich
can be usedforpowering the electricallock ofthedoor,ortheIPBell
doorphone can be poweredbyPoE(PoweroverEthernet).Featuresaresimilar
toahands-free telephone.Among the basicfeaturesyou can find possibilityof
opening twodoorviaelectricallocksand easyconfiguration viaWEB based
interface.
The producerimprovesthe programming toolcontinuosly(firmware).The IP
Belldoorphone canbe upgraded bythe latest version offirmwarewhichyou
can obtainon emailrequest. Forcontact details.
Necessary stepsforthe firmwareupgrade can be found inchapter3.1.10 on
page 34.Wesuggestyoutousethe latestfirmwareversion inorderto
exploit newfeaturesand patches.

Pushbuttons ofthe doorphone areprovided withnametags.The visitor
pressesadesired pushbutton,the doorphone picksup the line either
immediately(the pushbutton isnotthe firstdigitoftheaccesscode)orwitha
delay(timeperiod between induvidualpressesofthe pushbuttons)and dialsa
preprogrammed telephone number.The dialled numberdiffersonlyaccording
tothe set dialling mode of the doorphone:
