Configuring Call Forwarding from IIJmio Mobile Phone to Another Number

IIJmio offers a call forwarding service. I had a situation where I needed to use it, so here are my notes.

Reference

Notes

  • The call charges from the contracted mobile phone to the forwarding destination are billed to the call forwarding service subscriber.
  • Charges from the caller are also required.
  • When call forwarding is set up, voicemail becomes disabled.
  • You can specify the number of seconds before forwarding (default is 7 seconds).
  • After setting up forwarding, an announcement “This call will be forwarded, please wait a moment” plays.
    • Change the guidance settings as needed.

Steps

To change the forwarding time to 5 seconds and disable the guidance announcement, the following steps are required:
