SIP Phones

SIP (Session Initiation Protocol) is widely recognized as the standard of choice for IP Telephony. With established industry standards, manufacturer's products will be interoperable and telephony customers will have a wide range of choices. Aastra is dedicated to developing products based on industry standards so that our customers fully realize the benefits of moving to IP.

Users are free to use any SIP compliant phone on the market. However, Aastra’s 67xi series offers a wide range of features, and provide superior performance at an affordable price.

External Phones

In the course of a day mobile users encounter a wide variety of telephony devices. How do people know where to reach them? With Clearspan, users call people not numbers.

Calls can also be routed to multiple numbers either simultaneously or in series.

On the outbound side users can choose whether to place calls using the device or by using Clearspan Anywhere to route the call as if it they were sitting in their office.
