Unable to make voice call from adl_callSetup()

[tomb]

Hello,

I am using function adl_callSetup(“50198***”,ADL_CALL_MODE_VOICE) to make a voice call or data call:
Function return OK, but I cannot call anoter phone number:

I subscribe to adl_callSubscribe(MyCallHandler) to see what’s going on… And I get:

at+wopen=1
OK
OK, Data phone call has been succeed
ADL_CALL_EVENT_NEW_ID
ADL_CALL_EVENT_NO_CARRIER
ADL_CALL_EVENT_RELEASE_ID

What am I doing wrong? Am I missing something before calling adl_callSetup()?

The code is below:

const u16 wm_apmCustomStackSize = 1024;

s8 ret_value;

s8 MyCallHandler(u16 Event, u32 Call_ID)
{
    switch (Event)
    {

           adl_atSendResponse ( ADL_AT_UNS, "ADL_CALL_EVENT_RING_DATA\n\r");

    case ADL_CALL_EVENT_ANSWER_OK:

What happens if you try to call those numbers “manually” with AT commands?

What clearing cause do you see with AT+CEER ?

[tomb]

Well, I haven’t try with AT command, that will be next step.

When I type: at+ceer I got following error:

at+ceer
+CEER: Error 0

According to AT_command_Interface_Guide error is defined:

: call release cause (please refer to section “failure cause from
GSM 24.08 recommendation” in Appendix)

So in Appendix I found only this:

Specific Failure Cause for +CEER
Cause value Diagnostic
240 FDN is active and number is not in FDN
241 Call operation not allowed
252 Call barring on outgoing calls
253 Call barring on incoming calls
254 Call impossible
255 Lower layer failure

Where can I find Error 0?

Later I have tried:

atd501985**
+WIND: 5,1

NO ANSWER

+WIND: 6,1
at
OK
at+ceer
+CEER: Error 19

Or 19? What does it mean?

[tomb]

ok, seems that Wavecom documentation contains wrong information… On page 55 VOLUME2 in 12.9.3 Parameters and Defined Values should be GSM 04.08

Anyway I got GSM 04.08 with all codes from 0 - 127.

But after I have type: at+cfun=1

I got error 226 that is over the range of values defined in GSM 04.08.
Where is the definition for this Cause No.?

Where those numbers are taken from ?

240 FDN is active and number is not in FDN
241 Call operation not allowed
252 Call barring on outgoing calls
253 Call barring on incoming calls
254 Call impossible
255 Lower layer failure

When I try to make a call using AT commands still I don’t receive a ring indication on my mobile phone:

at+cmee=1
OK
at+wind=63
OK
at+cpin?
+CPIN: READY
atd501985**
+WIND: 5,1

NO ANSWER

+WIND: 6,1
at+ceer
+CEER: Error 19
OK

What am I doing wrong?
Example has been taken from APPENDIXES (Page 21):

2.2 Examples where a Voice Call is Originated
2.2.1 When the ME is powered on and the SIM PIN has been entered
AT+CMEE=1 Enable the reporting of mobile equipment errors
OK
AT+WIND=63 Ask to display the general indications.
OK
AT+CPIN? Is ME requiring a password?
+CPIN: READY product is ready
ATD0607103543; Make a voice call
+WIND: 5,1 Indication of call
+WIND: 2 Remote party is ringing.
OK Call setup was successful
Conversation…
ATH Release the call
OK

Thanks in advance for answers.

Hiya,

It’s my understanding that the Wavecom modem tries to make the call over the DATA bearer by default. If your mobile doesn’t have a DATA number (or your telco doesn’t support DATA calls to a mobile), the mobile won’t answer.

To force the Wavecom modem to make a call over the VOICE bearer, add a semicolon ( to the end of the number in the ATD command.

i.e. ATD12345678;

and see if that connects to your mobile.

Also, have a look a the BEARER commands in the AT command manual.

Let us know how you get on.

ciao, Dave

Hi Dave, Thanks for answer,

AT commands are working fine, I can make data call and voice call! Send files over XMODEM, etc…

Now I am going to use adl_callSetup() function and see if this is working as well.
I will have more question about redirecting data file from GSM to UART1 but I will open new topic for that.

Thanks a lot for help,

Best regards,
Tom

Hiya,

@tomb

Thanks for answer,

No Problems. I’d been stuck on this at some stage also.

@tomb

Great. Glad that your app is moving forwards.

ciao, Dave

@davidc

the Wavecom modem tries to make the call over the DATA bearer by default.

This makes sense: the AT command interface on any modem (not just GSM) is basically intended for controlling data calls…

To force the Wavecom modem to make a call over the VOICE bearer, add a semicolon ( to the end of the number in the ATD command.

This is not just Wavecom - it’s standard for GSM

GSM Flow openned
ADL_CALL_EVENT_SETUP_ERROR

What am I doing wrong? Shall I register to GSM network or subscribe to SIM?
I have no clue why I cannot call my second terminal. With AT commands I can without any problems.

Thanks in advance for help.

It looks like the SIM is registering on its own without the need of supplying a PIN. But it seems to me that you do the call too early. After at+wopen=1 the modem resets and you’ll need to wait until the registration with the network. you could either subscribe to the SIM services or the unsolicited +wind: 10 message, after that you should be able to make the call…

Or wait for +CREG: 2 or 5

Thank you Jan for help! I have subscribe for sim events after adl_sim_event_full_init I call adl_callSetup() function. It’s working fine!

Cheers,

@tomb

after adl_sim_event_full_init I call adl_callSetup() function.

SIM Full Init doesn’t necessarily indicate that you have network registration.

You should really be waiting for network registration before attempting any network operations - including making calls!

You are absolutely right!! Thanks for the addition, how could I have forgotten that

Hi there,

I have a related question, is it necessary to subscribe before callSetup? I mean:

adl_callSubscribe(CALL_VOICE_HANDLER);

then

adl_callSetup(“0912…”, ADL_CALL_MODE_VOICE)

or not? you know, I firstly subscribed the call service, then I used adl_callSetup, is it correct?

I ask this, because I receive this message: “CALL SETUP ERROR:515”, as you know it means that “wait, init or command set is in progress”, but I really don’t know if this was the cause or not!

any idea?

Hiya,

Have you checked that (a) the SIM has finished initializing; &(b) that you have network attachment?

[bandali]

it was exactly the problem!

tnx!

Hiya,

It’s a common complaint…Always check SIM and network connectivity before attempting network operations…
