Wow so may replies… 
Thanks guys. 
Well I’m more thinking something simplistic:
SuiteCRM <---- ----> Windows app <---- ----> Bluetooth <— ---> Android app ----> phone calls the cllient/prospect/lead.
(And we are not talking about any dial pads or the bloated apps which loads most of the SuiteCRM too with leads and stuff like that in the android - it just enables the Bluetooth connection between your pc and CRM so the lead’s phone numbers are clickable. So its just lightweight app for the connection itself)
It would just be a very convenient of doing the daily things. Loads of employees in companies have smartphones provided by their company/employer as part of their job and its a very common thing. Landlines are just more and more uncommon in offices these days. So its would be a logic thing to have CRM connection like that.
I agree that Asterix is amazing, but again one size doesn’t fit all. Changing to an Asterix system requires investments in new communication infrastructure from purchase to educating staff to l learn how to use it. And you would still install an app on their cell phones for the mobile staff etc.
Having the above simplistic solution would let you continue with your existing national phone operator which you might already have a very favorable deal negotiated with. So to continue to use that would come as a very natural to everyone because everyone already knows how to use their smartphones = no need to educate people which reduces costs too.
So that’s my 5 cents. 
Kind regards
