To the best of my recollection, nobody knew that Vito had sent Luca to infiltrate Sollozzo's circle...so normally, he would've probably been with Vito the moment he was shot (which Solozzo knew had to be prevented). If not then, he would've most certainly been reachable and at Vito's side shortly thereafter.
The Family knew it was highly unusual that Luca could not be contacted immediately. That's why they kept trying and grew more concerned with each unanswered call.
