I certainly would consider a paid service, if it were absolutely necessary. I do not think it will be, certainly have not explored all options yet. Our office phone bill was about $1000/month before switching to google voice. Certainly been there, done that.
I am not at all looking for support from google, or any company(service provider), quite the opposite would be preferred. I hope I was not unclear on that requirement.
To that point, I did have a mild success by following this thread
https://www.obitalk.com/forum/index.php?topic=7920.0;wap2With it, I was able to forward calls on a master phone to other phones via the OBi service, while first ringing the master phone "ph". But it still didn't work quite how I'd have thought.
I put a comma seperated list of each of the 7 slave phones to ring. Only the first 2 rang.
What I then tried was registering 3 phones with google voice. Each of the 3 "masters" can then have 2 "slaves" via Obitalk service. This gives a total capacity for 9 phones (more than my
, has less than 3 phones simultaneously registered (requirement was less than 5), and all 8 phones seem to ring consistently and simultaneously.
There is one down side to this technique. The 5 "slave" phones lose the granularity as to which line the incoming call was on. Additionally, at least using the technique here, each outgoing call is on the same line. Not the worst, but not the best. Better than what I had before, though.
I am going to look at using the obi device itself as a GV to SIP gateway, then just registering each of the slave phones as sip services to the local gv gateway. If this works I should be able to have my cake and eat it too.
If not I will look at simonics. Thanks for the tip about Oauth ( I saw another thread that specifically said they weren't using that, which was the genesis of my concern)
