Google Voice with obi508vs rollover 911 to PSTN
oak949:
Can I redirect all outgoing 911 calls to the PSTN port (connected to an analog line) ?
It is not clear to me how to do this and how to test this.
I have obi508vs setup with 4 Google Voice accounts, which work fine.
In order to support 911 calls, I thought I use one analog outgoing phone line and plug it in the PSTN port. If someone call 911, the call should get redirect to the PSTN port. Is this the default?
How to I set it up and how do I test this?

I don't think any of the frequent forum posters have a 508, so this is just going to be "male answer syndrome" guessing. The admin guide is somewhat ambiguous as to the exact function of the one PSTN line port. Page 7 of the admin guide says it's just for failover use (default if the 508's power is off), but elsewhere, it states that the default digit map does contain the default rule to use that PSTN port when dialing 911. See pp. 105-106:
http://www.obihai.com/docs/OBi508AdminGuide.pdf
Have you sent in a question to Obihai about this?
As for testing, all you could do would be to try it, and immediately explain to the 911 operator that you are testing your PBX's 911 configuration.

I don't own an OBi508vs and I'm a little confused by the specs. The chart show the OBi508vs having 8 FXS ports and zero FXO ports. You need a FXO port to connect to a PSTN line. If your OBi508vs doesn't have a FXO port, you will need to purchase an OBiLine adapter.
The OBi508 Admin Guide shows the following as the default phone port DigitMap:
([1-9]x?*(Mpli)|
[1-9]S9|[1-9][0-9]S9|911|
[67]XX|**0|***|#S4|#[0-8]|#9x|
**81(Mbt)|**82(Mbt2)|**1(Msp1)|**2(Msp2)|
**3(Msp3)|**4(Msp4)|**9(Mpp)|(Mpli))
The DigitMap has 911 defined, so you are good here.
This is the default phone port OutboundCallRoute:
{([1-9]x?*(Mpli)):pp},{#0:ao},{#1:ph1},{#2:ph2},
{#3:ph3},{#4:ph4},{#5:ph5},{#6:ph6},{#7:ph7},{#8:ph8},{#:ph1,
ph2,ph3,ph4,ph5,ph6,ph7,ph8},
{(<6:park>XX<;s=1>):pk},{(<7:pickup>XX<;d=0>):pk},
{(<**82:>(Mbt2)):bt2},{(<**81:>(Mbt)):bt},
{**0:aa},{***:aa2},
{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},
{(<**3:>(Msp3)):sp3},{(<**4:>(Msp4)):sp4},
{(<**9:>(Mpp)):pp},{(Mpli):pli}
The outbound route doesn't have 911 configured, so add the following to the beginning:
{911:li},
This change will have to be made to every phone port OutboundCallRoute.
Use OBi Expert to make these changes.
You can do the following if you don't want to call the 911 operator.
For testing make the above change to ONLY the Phone 1 Port's OutboundCallRoute.
Using a RJ11 cord, connect the Line Port to Phone 2 Port.
Using the phone attached to Phone 1 Port dial 911.
The call should route out the Line Port, loop back to Phone 2 Port and then routed to the Primary Line for Phone 2 Port.
Since you don't have 911 service on GoogleVoice, the call will be rejected.
Check the OBi508vs' Call History to see what actually happened.
Edit:
I think the power outage failover is the same function as the old hardware version as the OBi110. When there is a power outage and you take the phone off-hook, you will get a dial tone from the PSTN line. The OBi544vs is the only 508 series box that has FXO ports, so this function only applies to it. The above is just a guess.

Like I said: it has a PSTN failover port. See the photo on page 9 of the admin guide.
The default digit map already has the rule for 911 dialing, so no modification should be necessary. See pp 105-106.
But again, this is all male answer syndrome answering. Ask Obihai for the official answer.

You are correct about asking OBiHai, but from some comments on the forum the OP shouldn't expect any useful help.
The spec chart for the OBi508vs shows zero FXO ports.
I missed the PSTN failover line on the chart.
The OBi508 demo config panels don't show Line Port definitions, so I wonder if calls can be routed to the failover port. I have a feeling they can't and the OP has to purchase an OBiLine.

oak949,
A question to ask is can calls be routed to the PSTN failover port
or
Is it used only during power outages to get dial tone on a PSTN line.
