Return Values Returns zero if the request succeeds or a negative number if an error occurs. Possible return values follow: • LINEERR_INVALLINEHANDLE • LINEERR_NOMEM • LINEERR_INVALADDRESSID • LINEERR_OPERATIONUNAVAIL • LINEERR_INVALADDRESS • LINEERR_OPERATIONFAILED • LINEERR_INVALCOUNTRYCODE • LINEERR_RESOURCEUNAVAIL • LINEERR_INVALPOINTER • LINEERR_STRUCTURETOOSMALL • LINEERR_INVALPARAM • LINEERR_UNINITIALIZED For lpForwardList[0].dwForwardMode other than UNCOND, lineForward returns LINEERR_OPERATIONUNAVAIL. For lpForwardList.dwNumEntries more than 1, lineForward returns LINEERR_INVALPARAM Note lineGenerateDigits The lineGenerateDigits function initiates the generation of the specified digits on the specified call as out-of-band tones by using the specified signaling mode. The Cisco Unified TSP supports neither invoking this function with a NULL value for lpszDigits to abort a digit generation that is currently in progress nor invoking lineGenerateDigits while digit generation is in progress. Cisco Unified IP Phones pass DTMF digits out of band. This means that the tone is not injected into the audio stream (in-band) but is sent as a message in the control stream. The phone on the far end then injects the tone into the audio stream to present it to the user. CTI port devices do not inject DTMF tones. Also, be aware that some gateways will not inject DTMF tones into the audio stream on the way out of the LAN.
