Using Google Voice Call Screening
flipdee:
Hi Stewart, jimates,
Thanks for your help with this one.
Stewart, I believe the location is the problem in this scenario. The obi110 will be in the UK.
I'm trying to achieve the nearly impossible I think, in order to give a semi-non-techie a way of screening out unwanted calls, the GV looks like the easiest all in one interface.
The issue really is the location, in having to bridge the UK pstn line to the GV USA number.
I suppose when GV finally reaches the UK it could be used in a much more reliable manner.
In response where screening will take place, for user friendly reasons it would be great for it all to take at GV, but I do understand why it us now preferable to happen at the obi.
It would be lovely if the obi could either check the GV white/black list in real time or keep a local copy that was kept in sync periodically.
Although, it's really the audio screening that is the killer feature as most unwanted callers will hide their cid..
So to use GV for everything but the white list may be a big ask.
Thanks again for your thoughts on this one.
My next best move may be to look for a how to on setting up freepbx or piaf as a substitute to GV, all features substituted locally on a thin client, although the cloud, one interface, hard to replicate.

Even if you get it to function correctly, IMO you won't be happy routing calls through GV. They'll be going twice over 8 time zones -- quality will be degraded and latency will be awful. Besides, while being selective about what calls ring your phone is a good idea, I don't see much value in screening schemes that involve a decision made by the callee; you still get disturbed on unwanted calls.
An example of a compromise solution, which adds no delay to calls between humans:
Set the OBi to fork incoming Line port calls to both a free Callcentric account and the Phone port, with the Phone port ringing delayed by three seconds. Callcentric's Call Treatments are set to send "good" calls to a busy singal (the Phone port will ring and CC will not be in the path) and "bad" calls to voicemail (the Phone port will not ring). During night hours, callers in the CC phonebook are good and all others are bad. During the day, anonymous and blacklisted callers are bad and all others are good.

Thanks Stewart,
I hadn't thought of a approach which delays the phone port ringing while another service does some call screening in the background
I believe that for certain groups of users, to give a solution which keeps the end user in "control" the screening option, while they are still "disturbed" by an unwanted call, the worst they are subjected to is a recording of the unwanted caller's name and then giving them the option to answer or hang up.
Another reason I am keen on the screening method is, under certain circumstances a legitimate caller may get dropped by a "non-screening" method, i.e they are with holding their cid without malicious intent.
I'm going to drop a post onto the PBXinaFlash Forum to see if anyone has setup an asterisk server to mimic gv screening features.
I'll give the callcentric option a go, this could be a "lite" screening option for slightly more confident end users.
Thanks again,

This works for me... I have my Verizon phone line set to forward ALL calls to my Google Voice number.
My Google Voice setup is set NOT to ring ANY Phone... neither the home phone number nor "Google Chat" (my Obi).
Then I have all the people I want to hear from in my Contacts, placed in Groups (Friends, Family, etc.), and those Groups are set to ring Google Chat.. NOT my phone.
My phone at home is hooked up to an Obi110 .. with GoogleVoice on SP1, and Verizon on the Line Port.
So all incoming calls go first to GV and only ring the phone, via Obi if they belong to a Contact Group that is set to ring Google Chat. All others go straight to voicemail.
All outgoing calls on the phone use the POTS line (Verizon) because I set SP1 to NOT be the primary outgoing line. So my friends see my real number when I call them, and 911 will know where to come if I call.
It all works well enough for screening, but I have a few issues with the VoiceMail indicator, which I discuss in another thread.
My wife is concerned about missing calls from people we haven't added, so I may need to work something out with rules to to screen the "Anonymous", and "Private Number", and "Unknown" calls that come through, while allowing other numbers that we don't have in Contacts to ring the phone...

Sorry, I meant to say, Is there anyway to retain Caller ID (CID) along the way with this configuration?
I'm in the same pickle. I've currently got the PSTN line forwarding to GV via CallCentric on SP2 by setting LINE->InboundCallRoute->SP(MYGVPHONENUMBER). This works great, except that all calls show up on GV and on the Caller ID as my outgoing CallCentric number.
I read that using sip calling would pass the Caller ID. GV no longer supports SIP calling, so I was planning on using "sp2(1777MYCCID@in.callcentric.com)" or, failing that, "sp2(MYINUM@sip.inum.net)". Then on CallCentric I set up all incoming to forward to my GV phone number.
Direct SIP is not working for me. When I try in.callcentric.com I get an error "End Call (483 Too Many Hops)". This seems to indicate that CallCentric is not honoring my forwarding request, though it does when I call the number from an outside line. So as a plan-B I tried calling my iNum that goes through CallCentric. The first time I tried it I got "End Call (503 Unavailable)" and then "End Call (500 Service Unavailable)" thereafter. Just as a sanity check, I used the echo test number for iNum (883510000000091@sip.inum.net) and it worked splendidly. I also manually called my iNum number using an outside line and it correctly forwarded to GV.
Any suggestions from the helpful folks here? Thanks!
