More Information
'With whom do I have the pleasure of speaking?' is the grammatically correct version. The use of 'whom' instead of 'who' is because 'whom' serves as the object of the preposition 'with'. Double prepositions should be avoided, so 'with whom' is sufficient.
Tips
A common mistake is to use 'with' at both the start and end of the sentence, leading to redundancy.
