Calls Since Maxon CIC was headquartered in Korea and its 2nd R&D in Thailand and the sales office in UK, the telecommunication costs for the call among its overseas offices was a big financial burden. The company had the offices in Korea and Thailand connected with a leased VoIP gateway, HS Telian (ITSP). Most employees, however, preferred PSTN based calls. The ITSP system was causing too many technical problems, and the voice quality was not acceptable. Mobility Needs In the headquarter, there always had been big needs for mobile voice and data service. It was believed that the mobile data serve in the meeting rooms and R&D center would substantially improve work efficiency. Unfortunately, the current system did not provide any mobile solution. Old legacy PBX Maxon CIC was using an old legacy PBX, which was purchased 6 years ago and in operation since then. The system needed an major upgrade.
