utilize auto attendant to answer or barge into PSTN line from obi110 SIP caller
rob613:
Is it possible to use an Obi110 in my home that I can call into as a trusted caller from a SIP phone, to answer my ringing PSTN line or barge in to join an existing call on the PSTN line?
The barge in feature requires entering # from the phone attached to the Obi phone port. The auto attendant uses # to terminate the dialing of a new number to call out to, and entering ## doesn't do what I am asking about here.
Perhaps there is a special code that I could specify in place of an outbound number that would have this effect?

While it's a simple task to bridge to the LINE Port from a SIP client or the Auto Attendant, LINE Port Barge In is a feature that's only available to the PHONE Port. Attempts to bridge to the LINE Port from any other endpoint or trunk will receive a BUSY if the LINE Port is currently in use (the LINE Port is considered in use as soon as an incoming call starts ringing).
rob613:
Is the line port considered busy, from the perspective a trusted SIP caller into the auto attendant, if the POTS line is ringing or was answered by an analog answering machine or phone in parallel with the obi on the home wiring?
That is the situation I am describing that I want to initiate a bridge remotely when someone has called my home.

rob613,
At the moment I think the only way you could join the conversation is if someone on the far end conferences you in. You would need a PBX or a sip account with at least 2 channels. If you are not at the far end, how would you ever know when to barge in?

A trusted caller is simply an InboundCallRoute rule that routes that CallerID to the Auto Attendant and nothing more:
Physical Interfaces -> LINE Port -> InboundCallRoute : {12341234567:aa},{ph}
The CallerID '12341234567' is considered a trusted caller and is routed to the Auto Attendant. There is no additional meaning or handling of a 'trusted caller'.
For additional info, see : Using Trusted Callers and Circle of Trust
The LINE Port is considered in use if:
1. It's ringing with an incoming call.
2. It has a call in progress on it.
3. An external device is off-hook.
