Confirm that the calling phone is not associated with your GV account and that Google Chat is the only forwarding phone enabled in GV.
On a failing call, what does caller hear? What is logged at GV? What, if anything, appears in OBi's Call History? Does phone connected to OBi ring? If so, what happens when answered? Does your cell phone ring? If so, what happens when answered?
Thanks for your reply. I just looked into things you suggested.
This is what's happening when someone makes a call to sp1 (GV): Instead of forwarding the call to SP2 and to my cell, the caller hears GV voicemail greeting after 5~6 rings. And this is what I see in my call history:
Terminal ID GoogleVoice1 SP2
Peer Number xxxxx(caller's #) xxxxx(my cell #)
Direction Inbound Outbound
09:45:20 End Call (403 Forbidden)
To me everything appears to be OK. Any idea why my cellphone wouldn't ring?
Of course, I can simply enter my cellphone info in GV as a forwarding number but I will have to pay international call rate since my cellphone carrier is not US based. On the other hand, my SIP provider is located in the same country as my cellphone carrier (cheaper rate than GV international calling rate).
