Do I need to replace my current guest room phones when upgrading the phone system, or can I keep them?

In many cases, you can keep existing hotel guest room phones when you change the telephone system. The key question is whether your current units fully support the features of the new platform, such as caller ID, message waiting lights, room status, and emergency dial behaviour. If not, upgrading selected phones as you modernise the system is usually the simplest way to ensure a consistent guest experience in every room.
