The ACS Service can help you meet the growing demand for SIP phones. Using the APMAX, ACS allows you to manage groups of multi-brand SIP Phones from the same UI that manages your other enhanced voice services. ACS gives you the option of provisioning quantities of SIP phones from your business office or from the customers location, right out of the box. The APMAX Web Portal option gives your customers the opportunity to change key phone settings for any of the SIP phones provisioned through the ACS service.
