notes

xopr had a look at the (poor man's) roaming option that is available. In short:

• you need a "pro" handset that allows multiple base stations (4 is mentioned); when registering to a base station, this option automatically passes by
• every handset needs to be registered to every basestation, so 24 registrations maximum
• I had some success using an old Profoon PDX-2900:
  • have base station registration activated before entering the PIN
  • press and hold ➡️\📞👤 for 3 seconds (🔋 and 🛜 (or 📞👤) will blink)
  • press and hold *️⃣🔕 for 3 seconds (it will prompt: bS-_
  • choose 1 to 4 (it will prompt: bS-4 PIN_
  • enter the base station's PIN code and finish with 📞
