Calling from car using bluetooth, call is placed on ril_0, even though ril_1 is default

[Jonas G. Drange]

What happened
Placed call from car over bluetooth
Call was placed on my first SIM card, even though I selected my second SIM as default for calls

What should have happened
The call should have been placed on my second SIM

I guess the problem here is that telephony-service is not involved in the process of placing the call: that's all done at the ofono level.
When telepathy-ofono (and thus telephony-service) get notified about the call, it is already placed in the wrong modem.

I don't know how this is handle inside ofono, but maybe there is a way for us to set a property saying which of the modems should be used when placing calls via HFP?

Actually, the call is started by a "Dial" DBus call to an ofono modem started from bluetoothd. Currently we are not using ofono's HFP implementation, but the BlueZ one. This will change when we move from BlueZ 4 to BlueZ 5. But for the moment the one which chooses the modem to use is BlueZ.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

Some research shows that audio/telephony-ofono.c in BlueZ 4 source tree only accounts for one modem in the system. Currently there is no way to specify a preferred modem.

[John McAleely (john.mcaleely)]

I agree, lets fix this when we move to bluez5, so I propose to defer this bug until then.

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

As a matter of fact I will also add that the slot chosen to start a call is kind of random and can change after a reboot. It would be possible to fix it in the code as a quick work around to have as a minimum a deterministic behaviour.

Knowing that this bug is in progress, I want to share an interesting finding (at least for me).

I am on rc-proposed (with bluez5, see details below). When SIM 1 is (randomly picked) used, the battery status is shown in the car display. When SIM 2 is used, the battery status shows 100% loading.

@Uranicus

Thanks for the heads-up re: battery status. The plugin that handles battery status currently doesn't properly handle dual-SIM. It's on our list to resolve before OTA9 is released.

Today I found out that outgoing calls on the bluetooth enabled Toyota Touch&Go system went out through sim2, although I have selected sim1 as the default for outgoing calls.

We need to get to the bottom of this one guys. What is the latest status? Users are still reporting the issue even though we've moved to Bluez5, so there is a still an issue.

[Tiago Salem Herrmann (tiagosh)]

Yes, this is still an issue. We agreed with Alfonso that ofono will use AccountsService to get the default sim card for calls.
It needs some work on telephony-service and system-settings.

[Robie Basak (racb)]

If this will take a while, then would it be possible to have ofono default to a deterministic SIM for outbound calls as an interim workaround? Eg. sort them by some key and take the lowest one, or use the lowest numbered port or something. Then I could swap the SIM cards around (if needed) to get the behaviour I need without having to wait for a full solution.
