In this seminar we shall expose the challenges of combining the two worlds: VoIP
and the traditional Signalling No. 7. We shall explore how these two
technologies can collocate together; we shall discover dedicated components and
protocols that were developed for connecting between these two worlds. In this
seminar we shall discuss different carrier grade topologies and analyze real
captures.
