providing the voicemail option. The providers use caller ID to automatically 
connect to voice mail number.

of the account by unauthorised callers.

untraceable. But as this is against the law, they use toll-free numbers along 
with caller ID.

• These white routes display the caller ID when the call connects to the 
recipient.

behind its high price is primarily the quality.

service gateways for traffic handling and call termination over the 
destination telephone network
