[Jonathan Cave]

OS version: channel: ubuntu-touch/rc/bq-aquaris.en vegetahd r1

Steps to reproduce:
 * giffgaff SIM in slot 2
 * Open phone settings go to call waiting section for slot 2
 * it read off
 * tested call waiting it was on
 * turned call waiting on using the toggle button
 * button now always read on
 * tried to turn off
 * button would never read off when returning to this page
 * call waiting function always on

Status changed to 'Confirmed' because the bug affects multiple users.

There are multiple bugs here, there is one bug that is UI related which has a fix pending for bug 1463841. The other issue I've seen is changing the voiceCallWaiting property on ofono can be flaky on krillin, and seems works on slot 2 than slot 1. I've reproduced this with the test-call-settings script, so that rules out libqofono and system-settings. I've also found that once I run list-modems once, it'll no longer fail to change the property. Here's the output of test-call-settings when it failed to change:

phablet@ubuntu-phablet:/usr/share/ofono/scripts$ ./test-call-settings /ril_1 VoiceCallWaiting enabled
Using modem /ril_1
Current Property values:
Network Status of Call Waiting - Voice: disabled
Network Status of Connected Line Restriction: unknown
Network Status of Calling Line Restriction: unknown

Unable to set property: org.ofono.Error.Failed: Operation failed

@ken-vandine, I have been trying on krillin (rc-proposed #59):

test-call-settings /ril_1 VoiceCallWaiting enabled
test-call-settings /ril_1 VoiceCallWaiting disabled

and worked well. I wonder if this depends on the operator. Could you attach the syslog when this happens?

@ken-vandine, thanks for the log, but I need more traces to determine the nature of the error. Please change /etc/init/ofono.override adding environment variables and "-d" to ofonod exec line:

<<
...
env OFONO_RIL_NUM_SIM_SLOTS=1

env OFONO_RIL_TRACE=""
env OFONO_RIL_HEX_TRACE=""

exec ofonod -d -P stktest,provision,sap,udev,dun,smart,hfp
>>

Then re-start ofono (on krillin: "restart ofono OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2"). In one terminal, execute:

$ sudo /system/bin/logcat -b radio > /tmp/radio.txt

And call the ofono script to change call waiting in another console. When it fails, please collect syslog and radio.txt and send those to me.
