MOT/Phone+

MOT/Phone+ is a powerful SIP client softphone app designed to transform your Android smartphone into an extension phone for your company's IP-PBX system. It supports high-quality audio codecs like AMRNB and SILK to ensure excellent voice quality even over mobile networks. Ideal for professionals wanting to integrate their mobile phone into their office's telephone network, MOT/Phone+ offers essential business call features such as call hold, attended transfer, call park hold, speed dial, and the ability to register with multiple SIP domains.

Compatible with NTT-HIKARI and Japanese ITSP (050 number) services, MOT/Phone+ enables seamless communication as part of your company's telecom infrastructure. Users should note that call reception via mobile networks may sometimes be delayed due to network conditions, and simultaneous use of other VoIP apps might cause conflicts. To optimize usage, a flat-rate data plan is recommended. The app collects access logs to the MOT/PBX server to assist with improvements, but does not track personal user information.
