Packet based vs "wire" based

One IP connection can carry

• multiple types of information

• and multiple phone calls

• all at the same time

Examples

• Voice plus text plus video– in two directions – all at same time

• Call someone and bring in relay in parallel later as needed

• Call someone and link in an assistant instantly as needed

• Invoke translators as needed to allow communication between people who all have different disabilities and sensory modalities.
