Thank you for this reply.

However, recall, that my software is a VoIP application which could
use different (a range of) multicast adresses during its lifecycle.
These addresses are allocated on demand by another software. Thus,
each instance is configured to be potentially linked to one of these
adresses. Furthermore, one can have many simultaneous VoIP
communications where each one uses one given multicast address. Except
if there is a solution to resolve this multiple multicast adresses
bindings, I can't see how this could be handled.

What do you think ?
