My examples shown here come from RonR's excellent guide to this subject:
http://www.obitalk.com/forum/index.php?topic=3094.msg20656#msg20656It's important to say that putting a number in a Circle of Trust does two things only:
1. Allows that number to make outgoing calls through the OBi's PrimaryLine (single-stage dialing).
2. Allows that number to use the OBi's Auto Attendant functions including making outgoing calls (two-stage dialing).
After accepting several Circle of Trust requests, the OBiTALK InboundCallRoute might look like this (assumes Primary Line is SP1 Service):
Voice Services -> OBiTALK Service -> InboundCallRoute:
{(290123456|200123456|300123456)>(xx.):sp1},{(290123456|200123456|300123456):aa},{ph}
The first rule allows single-stage dialling from any of the three CallerIDs. The second rule gives access to the Auto Attendant from any of the three CallerIDs. The third rule directs all other calls to ring the phone.
Any CallerID can be removed from any rule selectively. For instance, remove 200123456 from the second rule:
{(290123456|200123456|300123456)>(xx.):sp1},{(290123456|300123456):aa},{ph}
Now all functions are the same except 200123456 no longer has access to the Auto Attendant.
