Search query with wildcard

Hello, I'm trying to create query that will search for strings like

/v1/accounts/voice/code/+48123456789

/v1/accounts/voice/code/+48123123123

/v1/accounts/voice/code/+[48whatever that has 9 digits]

The condition is that the string must contain fixed part /v1/accounts/voice/code/ and wildcard for
48 [+ any 9 digits].
I tried query like voice/code/48?????????, but it lists all matches with strings between slashes.
I tried also to escape shash characters in search query, but then it will not list anything.
The problem is probably on shash, because itself its cosidered as special character, not marked (yelow) in search result, but if i escape it, then result is empty.
Can somebody quickly provide me with the right quer ?

What are you using for the query? KQL or Lucene?
