We're a UK based cleaning company and we want to digitalise our communications by moving our telephone systems to voip, principally so we can integrate it with Zoho in order to give us greater oversight and control. Logging calls, facilitating sales, easily creating tasks from telephone conversations etc. 

We also need something that encompasses SMS - at the moment we have mobile phones which we use to mainly contact cleaners / potential recruits - it's very messy so any system that can integrate with our CRM and allow us to bulk send SMS, archive SMS and index SMS against cleaner records within the CRM would be key.

I've looked at the options Zoho have and have struggled to find an ideal fit for a UK based business - does anyone in a similar position have any experience or recommendations for a potential supplier that integrates natively with Zoho?
