What it means
In Factur-X and ZUGFeRD Extended, each ram:TelephoneUniversalCommunication inside ram:DefinedTradeContact of the line's ram:ItemSellerTradeParty must contain one ram:CompleteNumber. The test counts elements, not numbers written within a single element.
Why it matters
Each telephone communication block has one number field in the required XML structure. Missing or repeated number elements do not match that structure.
How to fix it
Correct ram:TelephoneUniversalCommunication inside the line seller's ram:DefinedTradeContact. Add the missing ram:CompleteNumber or remove duplicate elements, leaving one with the intended phone number. Export the corrected file and check it again.
