# Can phonons induce non-$s$-wave superconductivity?

In BCS theory the interaction is considered isotropic and the result is an $$s$$-wave superconductor. Is it possible anyway for unconventional superconductors to have SC driven by phonons (I intend this as a material that shows isotopic effect but enlight me if I'm missing something) and a non-$$s$$-wave symmetry? Are there some materials showing this two properties?
