Aastra has a demonstrated commitment to developing solutions based on open standards which do not restrict the customer to a closed architecture or vendor lock-in. With open standards, customers can more easily integrate components to build a best-of-breed communication solution, or they are able to develop their own uniquely customized solution.
Aastra was among the first vendors to launch systems supporting SIP (Session Initiation Protocol) which has become the de-facto standard for IP network access, converged multimedia applications and low-cost IP endpoint devices. Aastra supports SIP across all of our product lines including:
- Pure SIP PBX solutions
- Hybrid PBX solutions which make it possible to add extensions or replace existing phones with cost-effective SIP phones from Aastra or third parties
- SIP Trunking to allow companies to reduce telephony costs and better manage their SIP voice and application trunks
- A comprehensive suite of SIP terminals, including SIP DECT solutions
- SIP-based applications such as multimedia contact centers and video conferencing solutions, which can be connected to any SIP compliant telephony system from Aastra or other vendors
In addition to SIP, Aastra’s solutions provide enterprises with open standard interfaces to integrate other telephony and back office solutions, including:
- XML
- CSTA
- SOA/Webservices
