Call hunt with two obihai 202 devices
azrobert:
You answered all my questions except one, but I don't need to know the answer now.
I'm going to use this post to explain the problem and my solution. I'll re-post the configuration changes separately with some additional info.
Problem:
Normally you can only forward a call once on the OBi202. The forwarding parms are defined on the SP trunk, not on the phone port. When a call is forwarded to PH2, there aren't any forwarding parms on PH2 so the call can't be forwarded again.
Solution:
Instead of forwarding the call to PH2, you can forward the call to a SIP URI address. Normally you would do this to route the call to another device, but I'm forwarding the call back to itself. I defined a dummy trunk on SP4. I forwarded the call to the IP address and port of SP4 on OBi202#1. The call goes out SP4 and loops around back to SP4. The X_InboundCallRoute on SP4 sends the call to PH2, so the forward is complete. Now you have forwarding parms on SP4 to forward the call again to OBi202#2 via the OBiHai network. A little complex, but it should solve your problem.
azrobert:
OBi202#1
Voice Services -> SP1 Service
X_InboundCallRoute: ph1
CallForwardOnBusyEnable: Checked
CallForwardOnBusyNumber: sp4(fwd@127.0.0.1:5063)
CallForwardOnNoAnswerEnable: Checked
CallForwardOnNoAnswerNumber: sp4(fwd@127.0.0.1:5063)
"Voice Services" and "SP1 Service" corresponds to the tabs on the left side of the OBi Expert page.
Click on Voice Services then click on SP1 Service
Now change the parms.
Both boxes to the right of the value must be unchecked to be able to make changes.
After all changes are complete for this page, click Submit and wait until the OBi202 reboots.
Now do the same for the following:
Service Providers -> ITSP Profile D SIP
ProxyServer: 127.0.0.1
X_SpoofCallerID: Checked
Voice Services -> SP4 Service
AuthUserName: OBi202a
X_RegisterEnable: unchecked
X_ServProvProfile: D
X_InboundCallRoute: ph2
CallForwardOnBusyEnable: Checked
CallForwardOnBusyNumber: pp(510222222)
CallForwardOnNoAnswerEnable: Checked
CallForwardOnNoAnswerNumber: pp(510222222)
Change 510222222 to the OBi number of OBI202#2
Physical Interfaces -> Phone 1 and Phone 2:
CallWaitingEnable: Unchecked
OBi202#2
Voice Services -> OBiTalk Service
InboundCallRoute: ph
CallForwardOnBusyEnable: Checked
CallForwardOnBusyNumber: ph2
CallForwardOnNoAnswerEnable: Checked
CallForwardOnNoAnswerNumber: ph2
Physical Interfaces -> Phone 1:
CallWaitingEnable: Unchecked
Edit:
Disable call forwarding in Phonepower.

I didn't see your latest post. I'll review it and test them out.

A SIP URI is basically the IP address of a device plus some additional info.
A dummy trunk is a fake trunk. It doesn't connect to any provider. It is needed for the call routing.
Forwarding number sp4(fwd@127.0.0.1:5063)
SP4 - I'm using the dummy trunk defined on SP4 to forward the call to the supplied address.
FWD - This is a dummy name and is ignored. It is needed for the syntax of the command.
127.0.0.1 - This is loopback address. It is the equivalent of specifying the IP address of OBi202#1.
5063: The port number of SP4.
The call is forwarded out SP4, loops around and comes back into the same SP4 on OBi202#1.
SP4 will send the call to PH2 on OBi202#1 via the inbound call route.
This is how the call is forwarded from PH1 to PH2 on a busy.
OBi202#2 is not involved up to this point.
On a PH2 busy the forwarding parms on OBI202#1 SP4 will forward the call to OBi202#2 using the OBiTalk network.

I followed the instructions and it actually worked! At first it wasn't working right because of the call on forward on no answer was enabled. This option made the phone going crazy, long story short once I turned this off everything worked perfect. Now it'll transfer on busy and no more over lapping lines. Thank you very much for your help!!!
Now I have one more follow up question. I really like to use GV voice recorder and its awesome transcription. Is there an option to program it so when someone calls phonepower SP1 it will simultaneously call GV SP2? This way Phonepower and GV both ringing, after 25 secs GV voice msg will kick in? Also, I don't want GV SP2 to ring at all when a call is being forwarded to it b/c SP1 will be ringing too.
Right now I get around this by using Ring.to to fwd simultaneously to phonepower and GV. However, I want to reduce another layer of potential hiccup. Hopefully Obihai has an option that Ring.to can do.
