If you have a bt device capable to make call only for last number you have called so without google voice key,you can try this flow for use google voice command.
If you can't use microphone of headset,open google app and in setting select use bluetooth headset.
Blocks 44 & 45 : set your bt device here
Works with a fake call and you see this on call log.
If you want go to automate setting and increase outgoing call limit
Feedback is appreciate
Do you have a better solution?You are wellcome!
