No. Call the Callcentric number from some other phone, not your wife's number. Perform several tests:
Call the CC number. It should ring on the OBi-attached phone. Answer it after two rings (don't wait for it to go to voicemail). Does that simple phone call work, with two-way audio (both parties can hear the other talk)?
If so, call the CC number, again from that same unrelated phone number, but let it go to CC VM. Use a timer to see how long it rings. Start counting from the time the calling phone hits "send" or "call", or dials the last digit for a land line. It should take at least 30 seconds before going to CC VM. What happens?
If, and only if, this works properly, then call your Google Voice number from that same unrelated phone, not from your wife's phone. Repeat the two tests (call and answer after it rings twice, and call and wait for it to go voicemail). The expected behavior is:
- For the human-answered call to the GV number, you should hear the prompt from Kiki to press 1 to accept the call, or press 2 to send it to voicemail. Sample of Kiki's voice: http://googlevoiceblog.blogspot.com/2010/06/new-voice-of-google-voice.html
- For the unanswered call, you should be sent to Google Voice's voicemail, and be able to leave a VM message on your Google Voice account.
