Hello 
,
I just realized that when I call by phone a Q2687 modem involved in a GPRS connections I don’t see any RING and the autoanswer (ATS0=1) don’t work.
It seems, from the point of view of the caller, that the modem is not registered at all 
My application needs that audio calls have precedence over GPRS: even if GPRS is currently connected in a FTP download (via WIP), an incoming audio call should be considered as more important.
I don’t even know if this is a feature that I should ask to the telecom I use or if it’s a feature that I can enable via AT…
Does anybody can help me, please 
Thank you in advance.
I accept and issue voice calls in my GPRS using app. like this:
At app. initialisation
adl_atCmdCreate(“AT+WDDM=0”…)// to disable DTMF tone recognition, it kills RING message.
adl_atUnSoSubscribe("+CLIP:",voiceClipHndlr); //see AT commands doc. on +CLIP message
In
voiceClipHndlr(adl_atUnsolicited_t * resp) {
//when response contains VOICE:
if( strstr(resp->StrData, “VOICE”)){//don’t answer DATA calls
gprsStop()//close sockets, stop bearer, wip_netExit(), at+cgatt=0
adl_callSubscribe(callHandler);
adl_callAnswer();
}
In callHandler()
adl_callHangup()
adl_callUnsubscribe()
gprsStart()
on events: ADL_CALL_EVENT_NO_CARRIER, ADL_CALL_EVENT_NO_ANSWER, ADL_CALL_EVENT_BUSY, ADL_CALL_EVENT_HANGUP_OK, ADL_CALL_EVENT_SETUP_ERROR_NO_SIM, ADL_CALL_EVENT_SETUP_ERROR_PIN_NOT_READY, ADL_CALL_EVENT_SETUP_ERROR,
