e911 Backup/Failover
RonR:
Setting PrimaryLine to Trunk Group 1 would affect all other calls but would not affect 911 calls due to the OutboundCallRoute rule:
{911:sp2}
Changing this rule to:
{911:tg1}
and settiing the Trunk Group 1 TrunkList to : sp2,sp1,vg3
poses a problem of how to get the number sent to be 911 if SP2 is used or 1aaa2345678 is SP1/VG3 is used.
Everton:
Thanks Ron for your assistance as usual. I did make the changes you suggested and change the password on SP2 which causes the VOIP.ms Trunk to not register(or disable the SP2 Trunk). I then change 1aaa2345678 to my Mobile number to test and it kept telling me that I "...could not get a response from the service provider". So with SP2 not registered, it did not move to the next SP1 or VG3. Any further thoughts as to why it doesn't work? Thx.

Everton,
There's no real failover implmented in the OBi. The following change to the OutboundCallRoute, however, should provide alternatives if SP2 or SP1 are not registered or connected when the 911 call is placed.
Physical Interfaces -> PHONE Port -> DigitMap:
([1-9]x?*@@.|[1-9]|[1-9][0-9]|911|**0|***|#|**1(Msp1)|**2(Msp2)|**3(Mvg3)|**8(Mli)|**9(Mpp)|(Mpli))
Physical Interfaces -> PHONE Port -> OutboundCallRoute:
{([1-9]x?*@@.):pp},{(<#:>):li},{911:sp2},{(<911:1aaa2345678>):sp1},{(<911:1aaa2345678>):vg3},
{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**3:>(Mvg3)):vg3},
{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
Physical Interfaces -> PHONE Port -> PrimaryLine: SP1 Service
Service Providers -> ITSP Profile A -> General -> DigitMap:
(<123:1aaa1234567>|<411:18003733411>|<**3>1876xxxxxxxS0|<**3>011xx.|
<**2>18(00|88|77|66|55)xxxxxxx|(Mste))
I also took the liberty of removing 411 from the PHONE Port DigitMap as it serves no purpose and I revised the ITSPA DigitMap for a more compact handling of toll-free numbers.

Everton,
It looks like the OBi isn't as smart as I thought it was. I assumed a service not being ready would be skipped in the OutboundCallRoute and the next rule would be tried, but it appears not to work that way and simply returns the error message.
RonR:
The only working solution I've come up with requires the use of a Trunk Group, but it's a little involved.
Physical Interfaces -> PHONE Port -> DigitMap:
((Mtg4)|([1-9]x?*@@.|[1-9]|[1-9][0-9]|**0|***|#|**1(Msp1)|**2(Msp2)|**3(Mvg3)|**8(Mli)|**9(Mpp)|(Mpli))
Physical Interfaces -> PHONE Port -> OutboundCallRoute:
{(Mtg4):tg4},{([1-9]x?*@@.):pp},{(<#:>):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},
{(<**2:>(Msp2)):sp2},{(<**3:>(Mvg3)):vg3},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
Physical Interfaces -> PHONE Port -> PrimaryLine: SP1 Service
Service Providers -> ITSP Profile A -> General -> DigitMap:
(<E911:1aaa2345678>|<123:1aaa1234567>|<411:18003733411>|<**3>1876xxxxxxxS0|<**3>011xx.|
<**2>18(00|88|77|66|55)xxxxxxx|(Mste))
Service Providers -> ITSP Profile B -> General -> DigitMap : (<E911:911>|...)
Voice Services -> Gateways and Trunk Groups -> Voice Gateway3
DigitMap : (<E911:1aaa2345678>|...)
Voice Services -> Gateways and Trunk Groups -> Trunk Group4
Name : 911
TrunkList : sp2,sp1,vg3
DigitMap : (<E>911|E911)
I have this implmented using a TrunkList of : li,tg1
(Trunk Group 1 has a TrunkList of : sp1,sp2)
911 goes out the LINE Port, but rolls over to SP1 using a replacement number if the LINE Port is disconnected. If SP1 is not connected, it rolls over to SP2 using a replacement number.
If you support 911 calls from an external phone connected via SIP, don't forget its InboundCallRoute rule:
{pap2>911:sp2} -> {pap2>(Mtg4):tg4}
Everton:
I made the changes suggested and using by Mobile Number for (1aaa2345678), I first disable SP2. and dial 911. The call was sent to my Mobile Number as required....GREAT!!!!
I then proceeded to disable SP1, in addition to the already disable SP2. I now getting ...."no service available to receive your call", which means the VG3 rollover is not working as plan. Maybe I am not following you where you said:

In my case, I have nothing connected to the LINE port and I have:
Trunk Group 1 has a TrunkList of : sp1,sp2
I to not have any reference to tg1. Where would I enter tg1 in your previous post....I think this is where the disconnect is!
Again, I have everything identical to what you described in your previous post. We are close, I just need to get the VG3 rollover working as an additional backup. Thanks again for your assistance!
