Bridge Incoming calls on PSTN Line with SP1

Is there any way/service like Google Voice which will showing the actual Caller ID when incoming PSTN call is bridged?
GV will not let you spoof the caller ID, though there are many paid services that will.
Unfortunately, there are a couple of potential problems. One is that the OBi's spoof feature is limited to sending caller ID in the From header, so that conflicts with the majority of providers that require your account number there. I believe that Flowroute may be an exception, but I'm not their customer and can't say for sure that it will work. They offer a small credit at signup, so you could test it without making a payment. CheapVoIPInc might also work this way; see http://www.dslreports.com/forum/r27236116-CheapVoipInc-Beta-testers-needed- for possible free trial.
Another option is services such as AlcazarNetworks or Voxbeam, which use IP authentication. I've used Voxbeam with the OBi in a setup similar to yours. For heavy volume, AlcazarNetworks is attractive for forwarding to a US mobile; the rate is probably less than $0.002/min. Try your number at http://www.alcazarnetworks.com/termination.php . Both of these offer free trials, but AlcazarNetworks is limited to 24 hours, which may not be enough to complete your testing, so you might use Voxbeam for debugging.
A separate issue is that I've never been able to make the OBi rewrite a caller ID, e.g. to prefix the number with a country code. Depending on what format your PSTN provider sends, and what the bridging provider accepts, that may or may not be a problem.

I have problem with my Obi110 where it won't forward incoming calls from PSTN (connected to land line) to my US cell phone using SP1, this Obi110 is in Indonesia and I am in USA. Also for all incoming calls from PSTN, nothing has been recorded in the call history as well, however the "LastCallerInfo" shows the incoming phone number.
I have been in contact with Obihai Support team about this issues and they want me to go to this forum and see if someone else have similar problem.
This are some of the settings:
Physical Interfaces > LINE > LINE Port > DigitMap: (xxxxxxxS4|1xxxxxxxxxx|xx.) -->Default value
Physical Interfaces > LINE > LINE Port > InboundCallRoute: {sp1(11231231234)}{(x12345678|x.12345678901):aa},{ph}
Physical Interfaces > LINE > LINE Port > RingDelay: 6000 (change to 6 seconds to detect caller ID)
Physical Interfaces > LINE > CallerIDDetectMethod: DTMF(Finland,Sweden) --> this seems to show the incoming PSTN phone number
Physical Interfaces > PHONE > PHONE Port > PrimaryLine: PSTN Line
I have tested to simultaneously ring for all incoming calls to SP1 to ring on my cell and it works just fine, however this is not working for the LINE / PSTN line. I basically modified the "X_InboundCallRoute" on the SP1 to {sp1(11231231234)},{ph}
I appreciate for any inputs/suggestions.
Thanks!

Your method for forwarding looks fine. It may be just a typo but you missed a comma here:
Physical Interfaces > LINE > LINE Port > InboundCallRoute: {sp1(11231231234)},{(x12345678|x.12345678901):aa},{ph}
This problem is all about Caller ID. If it does not show up in call history, then the Obi has not processed it for some reason. “LastCallerInfo” does show that caller ID exists, but not that Obi has processed it.
Do incoming calls from PSTN get processed as you would expect with no caller ID? That is they should route to the Phone Port and ring the phone attached to the Obi. This will show in call history. If not then the problem may be with ring cadences, thresholds etc.
If the incoming calls do get through to the Phone Port, then there is a problem with caller ID. It maybe the format of the caller ID, or it might be the ring “off” period is too short for the Obi to collect caller ID. Lots of things come into play here.

Ianobi, thanks for the input. There is typo on my previous reply, I did put a coma between the {} for my InboundCallRoute value and still have the same problem.
I reset my Obi110 again to factory setting and still having the same problem. The Obi110 is in Indonesia and I tested by hooking the land line directly to the Obi110 and thru splitter as well.
Here are the problems:
1) Set the Physical Interfaces > LINE > LINE Port > InboundCallRoute: {ph,sp1(11231231234)} and no incoming call from PSTN line were forwarded to 1231231234 using sp1. I tested using the same setting for sp1 and it worked just fine.
I tried changing the CallForwardUnconditionalEnable on the Physical Interfaces > LINE > Calling Features and it failed also.
2) It appears that the phone connected to the Obi110 Phone does not ring for all incoming calls from PSTN. It rings for all incoming from sp1 and sp2 using GV. I can make outgoing calls using PSTN, sp1 and sp2.
As Ianobi suggested, Obi110 does not process the calls from PSTN line, however the led light are blinking when there is incoming call to PSTN line.
Are there any other area that I will need to be tested to make this work?
ianobi:
This does seem to be a problem with your OBi detecting the incoming ring on the Line Port. The voltage may be low coming in from line, or is being lowered by devices connected in parallel with the OBi. Try a lower setting for:
Line Port > Ring Detection > RingThreshold
