Description
An ESI Communications Server is a powerful tool around which you can build your organization’s entire telecommunications strategy – and you don’t have to know it all in advance. That’s because an ESI Communications Server – the ESI-1000, the ESI-600, the ESI-200, the ESI-100, or the ESI-50- can be a traditional digital business phone system, a fully standards-based IP telephony system, or any mix of the two. The choice is entirely yours, and the mix can easily change when your needs do.
