Google Voice™ Service
OBi device includes a native implementation of the Google Talk™ (XMPP) protocol that allows the user to use the Google
Voice™ communications service as the SP1 or SP2 service (not available on OBi302). To enable Google Voice as the SP1 or
SP2 service, set the underlying ITSP Profile’s General::Protocol parameter to “Google Voice” (the default value of this
parameter is “SIP”). Both SP1 and SP2 can be enabled for Google Voice, with a different account on each service.
Google Voice offers a call screening feature such that you must press digit 1 before answering an incoming GV call. OBi
device can be setup to automatically do that for you when you pick up the phone. To enable this feature on the device, set
the X_SkipCallScreening parameter to YES (default is NO) (on the device web page, under the SP1/SP2 Service –
CallingFeatures section).
Please note that the codec is limited to G711u only for all calls.
When Google Voice is selected as the protocol, all the other ITSP Profile parameters are ignored except the DigitMap
parameter. The following SP1/SP2 Service parameters are also ignored:
- X_Codec_Profile, X_RegisterEnable, X_UserAgentPort, X_SipDebugOption
- X_KeepAliveEnable, X_KeepAliveExpires, X_KeepAliveServer, X_KeepAliveServerPort, X_KeepAliveMsgType
- URI, MaxSessions, X_AcceptDialogSubscription, X_AcceptLinePortStatusSubscription
Starting with firwmare release 1.2, the following features are supported:
- MWI (Message Waiting Indication) and VMWI (Visual Message Waiting Indication) for Google Voicemail.
- Non-Gmail domain in account name for Google Voice Communications Service.
- Accept DTMF input from a Google Talk client entered by the user as text messages (only 0 – 9, *, and # will be
recognized by the device).
- Accept the setting of the parameter ITSP Profile A/B – General::DTMFMethod. The value can be either InBand or
RFC2833. Other values will be reverted to RFC2933. Default is RFC2833.
