using obi100 as an extension to an obi200

[bill-cary]

I have 4 numbers configured on an OBI200. I would like to connect my OBI100 via OBITALK to the 200 and use it to receive or make calls if the 200 is busy.
1. how to setup to fwd 200 to 100 when 200 is busy.

2. how to setup to dial **x..... from 100 thru 200 when 200 is busy on another line.
thanks

OBi200

Physical Interfaces -> Phone1 Port
CallWaitingEnable: Unchecked
ForwardOnBusy: checked
ForwardOnBusyNumber: pp(200222222)

Voice Services -> OBiTalk Service -> InboundCallRoute:
{200222222>(<**n:>xx.):sp1},{ph}

OBi100

Physical Interfaces -> Phone Port -> DigitMap
Add following after the beginning parenthesis:
**nxx.S3|

Physical Interfaces -> Phone Port -> OutboundCallRoute
Add following to the beginning:
{(<510111111*>**nxx.):pp},

Voice Services -> OBiTalk Service -> InboundCallRoute: ph

Busy will not be detected with Call Waiting enabled
Replace 200222222 with the OBi number of the OBi100
Replace 510111111 with the OBi number of the OBi200
Replace n with a number of your choice.

Dial **n8005551212 on the OBi100 and 8005551212 will be routed to SP1 on the OBi200.
