boolean function ( Phone arg0 ) { return ( arg0 . getPhoneType ( ) == Phone . PHONE_TYPE_CDMA ) ; }
return true if the current phone supports ecm `` emergency callback mode '' , which is a feature where the device goes into a special state for a short period of time after making an outgoing emergency call . on current devices , that state lasts 5 minutes . it prevents data usage by other apps , to avoid conflicts with any possible incoming calls . it also puts up a notification in the status bar , showing a countdown while ecm is active , and allowing the user to exit ecm . currently this is assumed to be true for cdma phones , and false otherwise . todo : this capability should really be exposed by the telephony layer , since it depends on the underlying telephony technology . or , is this actually carrier-specific ? is it vzw-only ? concode_field_sep String LOG_TAG concode_field_sep boolean supportsHoldAndUnhold concode_elem_sep boolean useShortDtmfTones concode_elem_sep boolean supportsAnswerAndHold concode_elem_sep boolean supportsNetworkSelection concode_elem_sep boolean supportsOtasp concode_elem_sep int getDeviceIdLabel concode_elem_sep boolean supportsVoiceMessageCount concode_elem_sep boolean supportsConferenceCallManagement
