Morphology
The meaning 'an additional telephone connected to the same line' is directly composed from 'extension' (an add-on or additional unit) + 'phone' (telephone). This is a literal, compositional pattern found across languages, so a B1 learner who knows both constituents can reasonably infer the MWE's meaning.
Etymology
Extension phone comes from the idea of an extra extension added to the main phone. Imagine the main telephone with another small phone in a different room so you can answer calls from more than one place, so it means 'an additional telephone connected to the same line'.
