Pfizer VoIP Enterprise SIP & Voice Service Improvements Projects

Via partnership with The Judge Group, the shift.upgrade systems team has assisted in the completion of two major VoIP projects for the pharmaceutical giant Pfizer.  First, we provided subject matter expertise by performing service migrations from legacy TDM public telephone services to AT&T’s IP Flex SIP services.  Additionally, we assisted in the project planning and upgrade of the Cisco VoIP phone system servicing Pfizer’s largest North American sites.
