sierra and ec20 say:

root@osmo-gsm-tester-rnd:~# mdbus2 -s org.ofono /sierra_1 org.ofono.VoiceCallManager.Dial 1009 disabled
[ERR]: GDBus.Error:org.ofono.Error.NotImplemented: Implementation not provided
root@osmo-gsm-tester-rnd:~# mdbus2 -s org.ofono /gobi_0 org.ofono.VoiceCallManager.Dial 1009 disabled
[ERR]: GDBus.Error:org.ofono.Error.NotImplemented: Implementation not provided

gobi has no such interface:

root@osmo-gsm-tester-rnd:~# mdbus2 -s org.ofono /gobi_3 org.ofono.VoiceCallManager.Dial 1009 enabled
[ERR]: There is no method with name org.ofono.VoiceCallManager.Dial on path /gobi_3!

See also https://git.sysmocom.de/ofono/tree/doc/voicecallmanager-api.txt as doc for the arguments: enabled/disabled refers to hide_callerid.

After using a Jolla phone to verify the QMI calls, it looks like the EC20 is rejecting a `Dial Call` request with `Internal Error`.

I've pushed my recent state to the branch voicecall on https://git.sysmocom.de/ofono/.

Please don't use anything under lynxis/*, those branches might get rebased and are in an unknown state.

So far I've tested it with a public operator:
- dial out, hangup
- receive call -> hangup
- receive call -> answer -> hangup.

It's failing with SierraW modems. I attach osmo-gsm-tester run output archive with log and pcap, it also contains ofono log for the time of the test as usual.

I start osmo-gsm-tester with -s debug -t interactive, then I select to use 2 modems, then I wait until both are registered, then I use "g" command to see the msisdns and I run manually:

# mdbus2 -s org.ofono /sierra_1  org.ofono.VoiceCallManager.Dial 24756 disabled
[ERR]: GDBus.Error:org.ofono.Error.Failed: Operation failed

The ofono log only outputs a few lines when I use the Dial method:

ofonod[4952]: drivers/qmimodem/voicecall.c:all_call_status_ind() Call 1 in state QMI_CALL_STATE_CC_IN_PROG(4)
ofonod[4952]: src/voicecall.c:ofono_voicecall_notify() Got a voicecall event, status: dialing (2), id: 1, number: 24756 called_number: , called_name
ofonod[4952]: src/voicecall.c:ofono_voicecall_notify() Did not find a call with id: 1
ofonod[4952]: drivers/qmimodem/voicecall.c:dial_cb() QMI Error 3
ofonod[4952]: src/voicecall.c:dial_handle_result() Dial callback returned error: Unknown error type

I also tested issuing a call with the same procedure, this time with modems EC20 --calling--> SierraW.

It looks a bit better, the voicecall object is created but it stops after a few fractions of a second. I attach complete output of osmo-gsm-tester+ofono as usual.

The sierra is rejecting the call with Reason: "Incompatible destination".

The setup messages has the following TLVs:
- Bearer Cap
- Calling Party
- Called Party

I guess it's because of "Called Party" has NPI & TON set to Unknown.
while the "Calling party" has TON unknown, NPI isdn/e.164,

When trying to create one of the sierra:
- try "ATD12345" => create a data call
- try "ATD12345;" => don't do anything

It looks that the sierra got the wrong firmware or nvram.

updating the firmware in https://osmocom.org/issues/2471

voicecalls should work on the sierra as well on the ec20. Can you please run the osmo-gsm-tester with those modems?

I can successfully a voice call between 2 sierra modems, but I need to add a sleep(5) and other small issues as explained in #2543 and #2549
