Why an ​​​​​ESI Hosted Solution from TSIowa is right for your business. 

Who is ESI? 

Why an ESI Hosted solution?  ESI phones are designed to work specifically with their eCloud Hosted solution making it the most integrated solution on the market.  They use the same ESI IP phones on their Hosted solution as they do on their On-Premise IP systems, providing continuity across their entire IP platform. 

Other Hosted service providers often use whichever SIP phone provides them with the best pricing; (i.e. the least expensive phone available at the time.)  In doing so, some features may be lost and the ability for your provider to make remote programming changes for these phones may be limited. 

Why an ESI Hosted solution from TSIowa?  First, as a prospective customer we do our best to help you make an informed decision regarding your communication needs. This includes providing an on-site demonstration of ESI’s Hosted service.  As a part of this process we work as a liaison between ESI and your IT personnel to evaluate and test your network to ensure the highest Quality of Service (QoS).  This is completed before installing a Hosted solution; not troubleshooting it after the fact.  

TSIowa provides local support throughout the implementation process. We don’t just drop the phones off for you to install.  We help place and test each phone to ensure that they are working properly. To ensure that your users adapt to the new system and use the great features you have just purchased, user training is provided for all users.

While ESI provides ongoing U.S.-based customer support, we remain available to supplement this with local support for our Hosted system users.
