282 Call Routing Part 2
If a user group is busy, an incoming call is routed to user group 16. If user group
16 is also busy,
• the caller in the public ISDN network will obtain the congestion tone after call
waiting has been rejected;
• the caller in the private leased-line network will obtain the congestion tone.
• a call from the public analogue network will wait until the subscriber is free
after call waiting has been rejected.
