With SIP you must add multiple devices in order to use the same extension for two differents phones for example.
Suppose you have an extension 2000, and you want to use this extension in your Desktop and Mobile phone, so, if you use SIP, you need to create two devices, e.g.: 2000_DESK, 2000_MOBILE.
As you may see when using SIP, you need to use different credentials per device.
In the case of PJSIP, you only need to attach one device to the extension, and this device credentials can be used on multiple devices depending on the max contacts defined.0
