Paging and hot desking

Hot desking: lets staff log in to any shared desk phone and take their own extension with them.

Item Meaning

Each code can be changed or reset to default.

Example scenario

Padma Net Support sets international calls to 10 per day and 30 minutes per day with alerts to the IT manager, blocks a known robocall prefix 0900 for both directions, creates conference room 800 for the Monday meeting, and turns on hot desking for the three shared reception phones.

Tips

  • Set the international caps before opening international routes.
  • Choose Required wrap-up only where it matters; it holds new calls briefly.
  • Give moderators a different PIN from members.

Troubleshooting

Problem Fix
"Your plan's room limit is reached." Delete a room or upgrade.
Nobody can start a conference Wait for a moderator is on but no moderator PIN is set.
Hot desk login does nothing The phone must have hot desking on and be online; it restarts within a moment.
A feature code does not work Check the code under Feature codes; some can be switched off.
