Case Study: COVID-19 vaccination sites.

AllTalk VoIP Phone & Virtual PBX is trusted to connect multiple COVID-19 vaccination sites across France. The rollout of AllTalk began at a single hospital.


The hospital was presented with a major operational challenge of running a COVID-19 vaccination centre.


The hospital urgently needed a local telephone number that could be answered by multiple call-handlers regardless of location, which would enable patients to book vaccination appointments.


Cellhire provided its AllTalk VoIP Phone & Virtual PBX solution with a single local number that automatically routed calls to multiple call-handlers wherever they were based.


The hospital successfully launched a single phone number vaccine appointment service using AllTalk. AllTalk supported multiple call-handlers using its AllTalk Smartphone VoIP Phone App and handled large volumes of simultaneous incoming calls.

"Professionalism, quality and reactivity are the three key words I would use to describe the AllTalk project with Cellhire. The powerful solution was produced within 48 hours and is simple for the users and administrators to use, it is a great service. Cellhire delivered server upgrades in real-time to be able to accept the large volumes of calls (more than 2,250 in 1 hour, 7,000 in 1 day). "Bravo et merci" as we say in French for the service and the customer care."
