Google Voice + VOIP Phone
Ectoplasmic:
I have Google Voice working fine (SP1) with an analog phone attached to the OBi100. I also have a Cisco IP phone SPA921 and would like to use that with the Obi100 and only GV if possible. I know how to set up the Cisco for SIP service, and I know how to force it to make/receive calls without registration, but I'm confused by this:
http://www.obitalk.com/forum/index.php?topic=2454.0
I'm not clear if this will allow me to use Google Voice with the IP phone. Can someone give basic instructions? I'm used to entering the SIP server, username, pword, and then it works on the SIP phone.
Ectoplasmic:
In my attempts to at least get the VOIP phone to ring, I put this in X_InboundCallRoute for SP1:
{ph,sp1(user@192.168.137.252:5060)}
And I disabled X_RegisterEnable. Analog phone continues to work, VOIP phone will not ring.

That won't work; the SPx you use in the Inbound Call Route must be set for SIP. Given that your SP1 is GV, you need
{ph,sp2(user@192.168.137.252:5060)}
If SP2 is already set up for a SIP provider, you should be all set. Otherwise, reread RonR's first post in the thread you followed.

I've tried many variations of what was listed in that thread. Problem is, I'm not looking to do anything more than prove the VOIP can even ring at all, and I don't believe it can.
I did this:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Voice Services -> SP2 Service -> AuthUserName : (any userid)
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
And all variations of
{sp2(user@192.168.137.252:5060),ph}
Frankly I don't think a VOIP phone can work with OBi100+GV. I can't make the Cisco ring, not even a chirp. I have no problem setting up the Cisco to use sipgate or pbxes, and then ring from the Google Voice number.

I have used the OBi with Polycom phones in the manner described and had no trouble. You need to see what's going wrong. For starters, what does Call History show (there may be a SIP error code, etc.)? If no luck, try SIP Debug, sending the output to your PC (use Wireshark or a syslog server to view). Or, use SIP Debug on the Cisco.
An alternate approach is to register SP2 to your PBXes account as a sub-PBX. With the Cisco registered as an extension, you can set it up for single-stage dialing on outgoing, and get caller ID to pass on incoming. My OBi is presently set up that way (I use IP phones exclusively and have nothing connected to the Phone port).
