I have GV defined on SP1 and set MaxSessions=1
The second call failed over to SP2, so MaxSessions does apply to GV.
Real life testing seems to be more reliable than the Admin Guide which says:
Quote
When Google Voice is selected as the protocol, all the other ITSP Profile parameters are ignored except the DigitMap parameter. The following SP1/SP2 Service parameters are also ignored:
- X_Codec_Profile, X_RegisterEnable, X_UserAgentPort, X_SipDebugOption
- X_KeepAliveEnable, X_KeepAliveExpires, X_KeepAliveServer, X_KeepAliveServerPort, X_KeepAliveMsgType
- URI, MaxSessions, X_AcceptDialogSubscription, X_AcceptLinePortStatusSubscription
I'm happy to admit that I know very little about Google Voice. Looks like I'm on about the same level of expertise as the Admin Guide :D

I did some more testing. I set Maxsessions to 3 on the trunk where GV is defined. I answered an inbound call on the phone port and made 2 outbound calls, one from an Android and the other from a softphone on a computer. If I did this correctly, GV will support a minimum of 3 concurrent calls.

azrobert, actually trying your original suggestion to see if I can failover in TG1 to GV channels of SP2, and SP3 and it doesn't seem to work. If I set MaxSessions=1 on SP1 I would expect it fail over to SP2 at the second call, but it doesn't. Moreover, if I change TrunkList to "sp2,sp3,sp1" (no quotes) in Voice Services -> Gateways and Trunk Groups -> Trunk Group1, the first call STILL goes out on SP1 as judged by caller ID on the called phone... What gives? This doesn't make sense to me...
azrobert:
Are you using OBiTalk or the local interface to configure your OBi202?
If you use the local interface to configure your OBi you must disable OBiTalk auto provisioning, otherwise OBiTalk will overlay any changes you make.
System Management -> Auto Provisioning
Under OBiTalk Provisioning
Method: Disabled
Check the OBi202's call history to see what trunks to calls are routed.
To access Call History:
Log directly into the OBi using the local interface.
Key the IP address of the OBi into a Web Browser.
Hit Enter
The UserID and default Password are both "admin".
Click Status on the left column.
Then click Call History.
Zopa:
All calls are in call history are routed via Google Voice 1, which is configured on SP1
As for which interface I use, I try to use the remote management via obitalk.com. Which way is better, btw? Isn't the only way to configure GV via a web authentication pop in ObiTalk "Google Voice Set-Up"? I though if I unchecked OBitalk Settings and Device Default checkbox, I can manually enter parameters. Does it matter which way to configure it? I like the idea of remote management, but if it makes something not work, I can do it locally.
