All in all I think "golden" solution here would be something in-between, example:Each contact card's number would have dedicated "Call via Vicar" button. Ideally Vicar buttons would only be available for international numbers, not all of them. Now depending whether Vicar itself would have one or more calling card profiles created:Single profile - "Call via Vicar" button would place a call straight away using that profile. Multiple profiles - "Call via Vicar" would trigger additional, simple dialog window with Vicar profiles listed which should be used for that paritcular call.
